Hello Joe

This appears to be confusion with the event firing sequence

If you do a SET EVENT TRACKING ON
at the point in you code where things appear to be going wrong
you will be able to see what is going on here.

It may be that you will have to use Lostfocus() instead of VALID() for some of your functionality.

Good Luck



>I have a textbox class object which I am using to build data collection text boxes and grids. I have tons of functionality in the class object to evaluate the data being entered (both alpha and numeric), determine color of text box depending on the data entered, automatically advance to next object if the input mask is met, etc., etc. My problem is this:
