Hi Dojo,

*** UPDATES INLINE ***

I like to execute a script based on any change in a table cell and also when the page opens.

On page level I added the Options and Execute shape data fields:

Options ExecuteSetsOnInit

Execute
Script:MyScript|Parameters:trigger=[param:1/400,2505,F3]|Options:NoConfirmation|SetTrigger=ValueChanged

=> param is DMA_ID/ELEMENT_ID,PARAMETER_ID,ROW_KEY

Is this correct? I read in the docs that in this case the row key is separated by colon

Update => Yes, the parameter subscription syntax is correct

The script is executed neither initially nor when the value changes.

Update => It is executed, but it does not change the session variable!

Note: I can execute the script with a visio shape click. And the script passes then the output to a session variable. But not when automatically executed. But when then script runs automatically by SetTrigger, it does not update the session variable with:

engine.AddScriptOutput(UIVariables.VisualOverview.CreateKey("ACTIVE_SYSTEM"), activeSystem);

Does this only work when executed by a user?

why do I want to this?
Instead of have a lot of the same complex multiple conditions combined, I just created a script which writes back a single output to display the shapes of the current active systems. I want to avoid to update many data fields if something changes like a parameter ID. I know I can use session variables for the IDs, but even then the conditions are not that easy to read and maintain then.
