>I don't think you can set a ControlSource to an expression. There are two ways to do this. One is to have textbox 1 update textbox 2 in its InteractiveChange or LostFocus event. The other would be to put THIS.Value=CDOW(THISFORM.TextBox1) in the Refresh method of TextBox 2. You'll still have to make sure TextBox 2 gets refreshed after TextBox1 is updated.

Okay, method two is the way to go. A refresh is done when the value in textbox1 has changed. Thanks.
