BabyPowder2u,
Sorry! The variable declaration was part of the original sub that I clipped this from, to demonstrate how to do this. That part wasn't germaine to your query, so I left it out of my post; just forgot to delete the Dim statement.

Yes, it is a safe habit is to enforce ALL validation rules in the Before_Update event procedure of the Form too. In fact, I now do this routinely, but didn't at the time I wrote the routine I pulled this from. Having said this, there are weekly MVPs on this site that have adressed this kind of problem using the After_Update routine! But I do now use the Before_Update sub. As I say in my signature tag, The is ALWAYS more than one way to skin a cat!
