Hi Steve,

Sorry it takes so long for me to get back, but Novell's Border Server does not like usernames and passwords. Sometimes I can't get on for days at a time to anything that requires a login.

>>I had to put THISFORM.ControlSource = "whatever" in my command button and also PUBLIC whatever in my Form Init where I do my calculations. Thanks for the clue. I was all around it, but couldn't find it.

May I suggest that you make A and B properties of the form instead of public variables. I thought the problem that you were having might be that they were going out of scope. The reason that form properties are better than public variables is that properties are available to everything in the form, but not to anything outside the form without specific reference (Calcform.A) But not making them public you can prevent some other object from being confused by them.
