hi.
this programm example is nice, but it doesn't seem to work, at least not for my origin version, and I tried it on different computers.
For your example to work for me, do I have to add global variables or something? I mean it is done for your example, but just copying your code doesn't seem to do the trick. The first time trying to run it, it seemed to work, there was a box saying the function was being processed or something, but trying to call the funktion (neither as myFunction nor as AddColumns) is useless...
Unfortunately that's not the first time an example-code doesn't work. And I tried numerous, even those that were meant to be self-sustained.

I hope you can help me.

Thank you,
conny
