accessing global variables in process flow using Variable

The flexsim documentation mentions that process flow "Variable" activity can be used to reference to global variables. However, I do not seem to be able to get/set the global variable successfully using this approached. The value is NULL returned in "Get Variable" activity. Did I do anything wrong?

Hi @pc neo, if you just want to get and set the value of a global variable in your model, you can do it as the attached model shows. It is not needed to use a the process flow "Variable" activity. If you want to use this activity, the variable should be a tracked variable or a process flow variable, not a global variable.

thank you. Indeed that is what I want.

I read the User Manual by right click on the "Variable" activity -> Help, it writes that global variable can be used with "Variable" activity and so I tried.

This appears to be a bug. In 18.1.2, it was working with global variables. In 18.2.2, it is not working correctly.
