The id columns appeard in all of the my combo boxes.
I didn't change aliases.
Nothing chancheg in the combo boxes.
I don't think that the problem in the code of the command button (any way I have about 950 lines in my command button code and I'ts a little problem to debug it).
P.S
maybe the following information will help:
I added the following lines in my load event of the form:

 use xxx again in 0
use yyy again in 0

And this tables is the row sorce for the combo boxes.
It's can help you to help me?
Thank you!
