Hi,
 
see my sample doc, I made a pop-up menu that fill the choosen year in a text field, but if user don't select a menu item the text field displays a "null" value.
 
How can I prevent "null" to be displayed?
 
Thanks.

Without looking at the file, why not add a condition that verifies the result of the dialog was not null before applying its value to the field?
