Destination empty
Hi again,
I'm still playing with the scripts provided in the help section, and I have another problem I was hoping for help with.
This is from the debug window:
For some reason the Destination comes up empty, so the script shuts down.
This is the complete script so far (haven't played around with the try/catch parts yet...)
The code
Results in the output
