I need to change the following:
Nz(DMax("[RFI_LN_NBR]", "[T_VMAC1_RFI_LINES]", "[RFI_PROJECT_IDENTITY_FIELD] = Forms![F_REQUEST_CONTACTS]![t_REQUEST_PHASE_ID] "), 0) + 1



To include the field "[RFI_SEQUENCE_NBR] = ME.T_RFI_NBR"  which is numeric.

How do I incorporate both criteria items into the DMax?  Thanks.
