. . . . . and finally . . . I ended up having three adjacent text fields working as if they were a time field as earlier - P1F1 - A2::E, P1F2 - A1::N, P1F3 - A2::E.
This time however no field formulae were used, just range checks: 0 to 23 for P1F1 and 0 to 59 for P1F3 The second remains a no value may be entered field containing the initial value ":" For calculation purposes I currently have a hidden Time field with the formula: convert["T99:99";P1F1 ":" P1F3] Michael _______________________________________________ Dataperf mailing list [email protected] http://lists.dataperfect.nl/mailman/listinfo/dataperf
