Combobox ! calling function

i’ve a function on a frame, and some code (on the same frame) calls that function, and that function runs correctly. now i call the same function from a combobox and the function doesn’t get called. do you know why? and how to solve this darn thing?
btw, in the combobox i’m using on(click){} i don’t like to use function for that…
thanks.

edit: i traced my code, the exec. ends up on the line where i call that function, but the function still doesn’t get called.
