Access strange Error

No idea when or where this is happening.  No idea what the code is that's failing....  This may be due to old code that has never run until now because the conditions to run it have just now been met.  Sounds like it involves a Click() event, or an ill-formed error handler or some other code that has moved the code execution to a subroutine that is ill-formed.

Given what we know - that the code has been working for years and now it doesn't - here's the only help I can give - what did you change?

Hi Mark. I deleted a button without deleting it's click event. I ended up just importing the form from a backup and deleted the same button and nothing went wrong. It may have been some kind  of corruption

thanks
