Hi Guys,
Please help me on this one, I know not where the error is coming from. I'm trying to update a record in a form that edits an equipment inventory, I could not paste the image so is kinda as follows:
I can edit any field but the TAG (which is the primary key). The error shown is:

000001

any advise will be good, I just can hit the issue.
Thanks in advance.
