Field data changing on its own
I have a field where the data is changing automatically, but I'm not sure why. The script I'm using / layout / field has been working fine for the last years. Only last week it started changing on its own. To best of my recollection I have not changed anything.
What its supposed to do:
AT the main menu I enter a date, then the script will bring me to another layout and look up all the "classes" for that date.
Here are the screeshots (with my script / debugger screen)
