>I have gone through allllll the editboxes, and I see no problems. The error doesn't identify, WHICH editbox, nor what part of the program...that's why I'm asking for help ob using the debugger - it may be able to identify WHERE the error is coming from...

Actually it is telling which editbox. Its name is "Edit1".

As per using the debugger, simply at a location before the error occurs (say just before Do form of the suspicious form) put a line:

set step on

However, debugger wouldn't be much of a help here since the error is occurring during the bindings (a point where you can't step into).

You could check in code searching the SCX itself. Something like:

use myFaultyForm.scx
browse for atc("Edit1", name) = 1  && and check the properties column for ControlSource
use 

And finally I will be watching this for the next 5-10 minutes. If you like to check it online using teamviewer, provide an ID and PWD.
