To All,
I found the problem. Thanks to Razzak and Mike for all their help on this one.
It turned out that a combo box on a form must have been corrupt in some way.
I tried most of the suggestions that people were kind enough to give here
and then started cutting away layers. I found that a simple one line
command file 'edit using form whe customerid = .value' would generate the
error if it was run three times in a row!
Once I determined that it was not the code, I removed the eep's from the
form. When the problem persisted I started removing controls from the
form. Luckily the first combo box I removed did the trick. I removed the
combo box, saved the form, recreated the combo box and it worked!
Again, thank you for all of the feedback.
Jeff
