80040e07--Data type mismatch in criteria expression
This error occurs when the server tries to process a page containing an Insert Record or Update Record server behavior, and the server behavior attempts to set the value of a Date/Time column in a Microsoft Access database to an empty string ("").
Microsoft Access has strong data typing; it imposes a rigorous set of rules on given column values. The empty string value in the SQL query cannot be stored in an Access Date/Time column. Currently, the only known workaround is to avoid inserting or updating Date/Time columns in Access with empty strings ("") or with any other value that does not correspond to the range of values specified for the data type.
