I am losing my mind. I have an event procedure attached to the after update event of a date field. When I revise the date field it executes the code, and if I tab between fields it is fine as well, as soon as I click in another field I get a Type Mismatch error, which is crazy since I have commented out all of the actual code. The error makes reference to the expression may not result in....or [Event Procedure] - which the date field is obviously using - so perhaps that is an issue, but the code works (when uncommented) and does not generate an error unless I click in another field (versus Tabbing).
