Hello colleagues

I need to open determined screen based on application variable value on ScreenMaker 5.14.  
It should be something like this:

If ApplicationVariable = “A” then OpenScreen 1  
If ApplicationVariable = “B” then OpenScreen 2

I get the value of application variable during RAPID execution  
I tried to use “Conditional Trigger” control, but with no success  
Maybe I donA’t know how to use it on the right way.

Can somebody help me with this case?  
Thanks in advance !!

Hello,

Conditional Trigger gets triggered if the condition is satisfied. I have tried to create a document describing a simple example on using conditional trigger which has a similar scenario.

Hope this helps.  
Thanks.

Hello !

Really thanks for your help  
It worked in my application

Just a question to clarify …  
What does “LHS” and “RHS” means ?

I would like to know what the acronym means …

Thanks once again !!

Hello,

Thanks for your inputs, here LHS stands for Left Hand Side and RHS stands for Right hand side.

If we have an expression like A EQUALS B or A GREATER B  
‘A’ would be the left hand side value to be compared with the Right hand side value ‘B’.

Hope this makes it a little clear.

Thanks
