Microsoft access forms
After I enter data in the field [barcode] of frm_lunch, I want to see if the value of mid([barcode],9,7) exists in [tbl_idnum].[grade].
If it does, I want to return to input on frm_lunch.
If it does not, I want to open form [pufrm_enterid] and pass the value of [mid([barcode],9,7) to [tbl_idnum].[grade]. and ask for input to field [tbl_idnum].[full name].
