Not quite sure whether my title is appropriate but my problem is as follows:
I have a form with two particular object fields that are related in the following manner:
Object 1 is a combo which selects an entry and the second object is a text box where I will input a date.
The combo can select from four different items but I what I want it to do is that if any three particular items of the four is selected then an entry has/must go in the date field and if it is not then some of message should appear.
The Access version I'm using is A97 and A03.
Grateful for assistance
