>I guess that I will have to do a work around like what you mentioned. The situation is that there are 10 different fields that I use for measurements, so I have 10 text boxes and corresponding labels. The problem is that there are 6 different types that use only certain measurement fields and they are not consistant about the order in which they appear. What I had done was to assign the controlsource, caption and visible properties based upon what the type is for each record. The problem is that for some of the measurements there needs to be code attached to the lostfocus event of the corresponding control.
>So... If I need to stick with this way of doing things, I need to create identical lostfocus events for the text boxes that test to see what the controlsource is for that text box and carry out the code if need be.

You probably may just evaluate TYPE("This.Value") in lostfocus event, or reset Control.Tag property as indicator.
