have also tried the below, but it didn’t worked : 

if (execution.getVariable('DiscountAmount') !== null) {
    true;
} else {
    false;
}

I made a simple workflow to test manually and i’m having the same problem

​@dsj ​@kamnlk ​@Lahirumala de Mel  if you have any ideas i will be greatfull 

Thank’s in advance 

Hi ​@IFSRUNINNOVAL ,

I quickly tried this scenario, and it seem to work for me

what it the condition you have for the other branch of that gateway ? if that is also true for this variable value that could cause issues with picking up the correct path to follow 

there is another alternative syntax you can use for expressions in these scenario 

${execution.getVariable("demoAmount") != null}

​@kamnlk and if you try demoAmount with no value will it work also please?

already tried the Execution.getVariable :/ 

Hi ​@IFSRUNINNOVAL ,

Yes it should also work in that scenario as well 

thank you ​@kamnlk mabey it’s related to my environment :/

Hi ​@IFSRUNINNOVAL 

I usually do the validations in a script before reaching the gate. it helps to build complex validations and keep the gate conditions clean, and work :D

For your scenario, use a script like this

In the gate, use the isValid variable as the condition

Valid path:

Invalid path

Hope it helps!

​@dsj thank’s.

Good idea!
