I’m wondering why I get a syntax error some of the time when I use IF statements with multiple ELSE IF conditions unless it has an END IF for each condition, but not every time. In my first example, I made a function that is comparing which gripper on my end of arm tool & which buffer nest are selected to pick or place a part with. When I use my IF statement with the possible ELSE IF conditions, it has an error unless I have an END IF for every condition. However in my second example, my proc has the main IF statement with two ELSE IF conditions (as well as another nested statement), but only required a single END IF. I’m not sure what is different about these examples that makes the first example need so many END IFs. Example 1: !\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* !\* Determine which position the robot is going to for the buffer nests !\* Depends on which buffer nest & which gripper is selected !\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ```auto FUNC num BNPosition(num nBufferNest, num nGripper) VAR num nBufferNestPosition; IF (nBufferNest = 0 AND nGripper = 3) THEN nBufferNestPosition := 0; ELSE IF ((nBufferNest = 0 AND nGripper = 2) OR (nBufferNest = 1 AND nGripper = 3)) THEN nBufferNestPosition := 1; ELSE IF ((nBufferNest = 0 AND nGripper = 1) OR (nBufferNest = 1 AND nGripper = 2) OR (nBufferNest = 2 AND nGripper = 3)) THEN nBufferNestPosition := 2; ELSE IF ((nBufferNest = 0 AND nGripper = 0) OR (nBufferNest = 1 AND nGripper = 1) OR (nBufferNest = 2 AND nGripper = 2)) THEN nBufferNestPosition := 3; ELSE IF ((nBufferNest = 1 AND nGripper = 0) OR (nBufferNest = 2 AND nGripper = 1)) THEN nBufferNestPosition := 4; ELSE IF (nBufferNest = 2 AND nGripper = 0) THEN nBufferNestPosition := 5; ENDIF ENDIF ENDIF ENDIF ENDIF ENDIF RETURN nBufferNestPosition; ENDFUNC ``` Example 2: !\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* !\* Move the robot home at the selected speed & zone !\* If the part has been inserted to interference, assembly must be moved clear !\* If the part has been partially inserted, it can be lifted straight out !\* If the part has begun glue/cure, it must be moved clear !\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ```auto PROC Home(speeddata HomeSpeed,zonedata HomeZone) !Slow home VAR bool bPreInsert; VAR robtarget pInsert; jCurr := CJointT(); pCurr := CRobT(\Tool:=tool1 \WObj:=wobj0); IF (EIP_OUT64 = 0 AND EIP_OUT65 = 0) THEN !Raise Z pCurr.trans.z := pHome.trans.z-1; MoveJ pCurr, HomeSpeed, fine, tool1\WObj:=wobj0; MoveJ pHome, HomeSpeed, HomeZone, tool1\WObj:=wobj0; ELSEIF (EIP_OUT64 = 1) THEN IF (bPreInsert = FALSE) THEN MoveL Offs(pInsert,0,0,+8),v300,fine,tool1\WObj:=wobj0; MoveL Offs(pInsert,0,+30,+8),v300,z0,tool1\WObj:=wobj0; MoveJ Offs(pInsert,0,+100,+50),v300,z10,tool1\WObj:=wobj0; MoveJ pHome, HomeSpeed, HomeZone, tool1\WObj:=wobj0; ELSEIF (bPreInsert = TRUE) THEN MoveL Offs(pInsert,0,0,+40),v100,z10,tool1\WObj:=wobj0; MoveJ Offs(pHome,0,0,0),v300,fine,tool1\WObj:=wobj0; bPreInsert := FALSE; ENDIF ELSEIF (EIP_OUT65 = 1) THEN MoveJ Offs(pInsert,0,0,0),v100,z0,tool1\WObj:=wobj0; MoveJ Offs(pInsert,+10,0,+50),v100,z10,tool1\WObj:=wobj0; MoveJ Offs(pInsert,0,+100,+50),v100,z10,tool1\WObj:=wobj0; MoveJ pHome, HomeSpeed, HomeZone, tool1\WObj:=wobj0; ENDIF ENDPROC ``` ---

I would say the obvious difference is example 1 uses ELSE IF Example 2 uses ELSEIF ELSE IF would be interpreted as an else statement containing a further IF statement ---

> [@EMInvio](#): > > `ELSE IF` That seemed to me peculiar and it stood out in your second example in contrast is “ELSEIF” like I have always seen in use. Try changing your first example to ELSEIF without the spaces and let us know, please. I really didn’t think that we could use it like that, with the space. ---

Example 1 is behaving as: IF (nBufferNest = 0 AND nGripper = 3) THEN ``` nBufferNestPosition := 0; ``` ELSE IF ((nBufferNest = 0 AND nGripper = 2) OR (nBufferNest = 1 AND nGripper = 3)) THEN ``` nBufferNestPosition := 1; ELSE ``` ```auto IF ((nBufferNest = 0 AND nGripper = 1) OR (nBufferNest = 1 AND nGripper = 2) OR (nBufferNest = 2 AND nGripper = 3)) THEN nBufferNestPosition := 2; ELSE ``` ```auto IF ((nBufferNest = 0 AND nGripper = 0) OR (nBufferNest = 1 AND nGripper = 1) OR (nBufferNest = 2 AND nGripper = 2)) THEN nBufferNestPosition := 3; ELSE ``` ```auto IF ((nBufferNest = 1 AND nGripper = 0) OR (nBufferNest = 2 AND nGripper = 1)) THEN nBufferNestPosition := 4; ELSE ``` ```auto IF (nBufferNest = 2 AND nGripper = 0) THEN nBufferNestPosition := 5; ENDIF ENDIF ENDIF ENDIF ENDIF ENDIF ``` ---

Yes! Thank you @mike_10 & @lemster68 that does seem to be it. Once I removed the space, it only needed the single ENDIF. I’m glad it was something that simple, even if I feel a bit silly for missing it. 😅 ```auto FUNC num BNPosition(num nBufferNest, num nGripper) IF (nBufferNest = 0 AND nGripper = 3) THEN nBufferNestPosition := 0; ELSEIF ((nBufferNest = 0 AND nGripper = 2) OR (nBufferNest = 1 AND nGripper = 3)) THEN nBufferNestPosition := 1; ELSEIF ((nBufferNest = 0 AND nGripper = 1) OR (nBufferNest = 1 AND nGripper = 2) OR (nBufferNest = 2 AND nGripper = 3)) THEN nBufferNestPosition := 2; ELSEIF ((nBufferNest = 0 AND nGripper = 0) OR (nBufferNest = 1 AND nGripper = 1) OR (nBufferNest = 2 AND nGripper = 2)) THEN nBufferNestPosition := 3; ELSEIF ((nBufferNest = 1 AND nGripper = 0) OR (nBufferNest = 2 AND nGripper = 1)) THEN nBufferNestPosition := 4; ELSEIF (nBufferNest = 2 AND nGripper = 0) THEN nBufferNestPosition := 5; ENDIF RETURN nBufferNestPosition; ENDFUNC ```
