Type Mismatch

[DBFIN]

I get a "type mismatch" error every time I open a form. Since I thought there might be a problem with the data, I deleted all records in the datasource as a test and reoponed the form. I still get the same message even though there is no data in the data source.

What is causing the "type mismatch" error and how can I fix this ?

All the combo boxes were working for over six months. I had a multi-tab form that I recreated into single forms by copying each tab form into a new single form. That's when the problem started.

I'm lost in this issue.

I recreated the forms with another copy paste and the problem dissappeared.
