OnStart: global variables set to values, but variables remain to be stored with "no value"

Dear community

I am struggling with setting some variables which I set with Set(varName, value). I am using the function CountIf to define the values. Further, I have set a simple variable Counter = 1:

As you see at the bottom when clicking into the CountIf field of n_KTP, Countif(ApplicationCollection, Machine="KTP1X") = 4. However, when I use the variables, like Counter, I figured they are not set to the values, but to "no value."

Using them in function within the app will logically always result in a value = 0.

Any ideas what I am doing wrong here?

Thanks

Thomas

I test that. It's working on my side, Make sure you Click Run On Start and then test.

What I have already figured is that it is related to the App.OnStart, which somehow does not initialize the variables.
If binding all the variables to "OnClick" of a button, these variables will be all set correctly.

You have to initialize it by clicking on "Run on Start"

Is this practical in a production environment? Am I gonna ask my users to Run OnStart before using the App (they do not even have access to it!).
Notice that Set and UpdateContext do not work either in OnVisible.

Open Issue: Where to place Set and UpdateContext functions so that we initialize our variables (no, they do not work in App.OnStart or OnVisible. They work, however, in a button's OnSelect.
