Awesome, thank you once again! Now it is fully clear.
A side question about scripts. Every time I modify a script (and I
assume I create one) and I save the denemo file, I get the warning
'You have a script defined, and the choice between Normal Save and
Advanced: Execute the script etc.
I always press Normal Save, but I'd like to understand what the other
option means and when it should be used.

Cheers,
