On my main form, I have a textbox which shows the workorder number for that record. The workorder number is an autonumber and the primary key in the underlying table. This number is generated every time a new workorder is created. Is there any way that if the user enters a different number in the workordernumber textbox, it will go to that corresponding record, and not change the value of the workorder number for the current record. Hope this makes some sense. I thought I could put something in the afterupdate, but can't figure out what.
