I have had this problem for a while. What I am attempting to do is when a record is changed, I set a field - DateTimeStamp to Now() in the BeforeUpdate EventProcedure of my form. But, when using a combobox to look up records on my form, I get this error message sometimes and don't understand why.

Does anyone have any ideas?

When you you get this error?

Is it agter you select a record to look up in the combobox?

What code do you have in the after update event of the combobox?
