I figured it out, although I do not know why it did not work.
I had a field named FormID in the table (and on the layout). It contained an auto entered serial number. I wanted it to display on the web page, but if I had it on the layout that i was using, I would get the error message in my original post. If I removed that one field from the layout, then everything worked.
I was NOT modifying the field. I just wanted it on the web page for reference. I do NOT know if the error was because of the name (FormID) or something else. I do know, that once I removed it from the layout that PHP Assistant was using, I was then able to edit the record successfully.

Thank you for your post, and I apologize for the late reply.
"formid" may be reserved, as it is used in other web languages. If you change the field name to FormID2 or Form_ID, do you still get the error? I don't have access to a server machine today to try this out. Let me know your results.
