hi I have 2 fields in my update query, one is txtPartNum and other one is txtBaanNum. txtBaanNumber I want to update, it should equal to txtpartNum. so what ever value is in txtpartnum, should update table, so that txtbaannum will have same value as well. when i view the query then it gives me right data, but when i click on run, then it does not update the table. why?
