The parameter script (or master as parameter script) will be run more than once so you need to trap it.
This should help do that.
From the GDL manual …
First Occasion in Progress
n = APPLICATION_QUERY (“parameter_script”, “firstoccasion_in_progress”, isFirstRun)
This command returns whether the current run is the first run or a consequence of a previous execution of the parameter script which changed
some parameters. This command has no additional parameters.
The distinction may be important when a part of the parameter script executes a triggered event – e.g. it handles the pushing of a function button.
isFirstRun: The returned value shows whether the current run is the first run
