>Is your rowsourceType set to alias or fields? If fields, what is the text in the RowSource property? If Alias, why?

The rowsourcetype is fields. The rowsource is 'V_sys.location,v_sys.state,v_sys.aff_id'.

Location is C(35), state is C(2) and aff_id is C(4). The aff_id is the bound column (3).

However, it doesn't matter what my rowsource or rowsourcetype are. If I change it to SQL-SELECT, ALIAS, or FIELDS all results are the same. It seems that tabbing into the combobox generates an "Expression Evaluator Failed" on large tables.
