Cond format based on if field value is valid

R

REGREGL

Hello all,

I have a combo box whos control source is a filed on a form,its Row Source
type is a query and its row source is a record from the query. Basically the
field on the form is a category ID number. The query compares that category
number to the list of category numbers and the end result is that the
category descritpion text is displayed on the form. I need that descritpion
combo box to change colors if the category code is not on the list of
available category codes.

How can I accomplish this?

Thanks for your advice....
