The GUI out of the script (solved)

[Dragonetti]

Hi
Sexan hasn't been on the forum since January, so I ask the community.
Can someone rebuild this script without a GUI.
My project manager has a problem with restarting the script when opening a new project.

Thanks

I take the Archie Counter, which works perfectly.
