Cause:
You deleted fields from the table
Resolution:
Either:
input the fields into the table in design view again
or
Delete the controls on the form
Reason:
The invalid control source is because that textbox (control) cannot find a field in the recordsource (the source table/query) with a matching name. Thus when you open it, access gives you the chance to manually input a value.
