I have an access 2007 database with a combo box that is filled with part number (which is also the uid) from its corresponding table. when you enter a part number that is already a record and then Tab out of that field, it takes you to that record, but when you enter a part number that doesnt exist and tab out it does nothing. Is there away I could make it display a message that says "the number you entered does not exist in the table, would you like to add it as a new record?" and then you could click OK and proceed with the entry? Your help on this one would be greatly appreicated.
