I have a tblMembers table. Sometimes if I try and change the name of a field by adding a couple of characters eg,(IDSponserFK to IDSponserFK99, Access locks the name and will not accept the 99 digits, Same for Field TYpe; I can select a different type but it will not accept it. Likewise if I try and change the field property from Integer to Long Integer. Anyone know what's going on????Thanks...
