User has two linked fields into a Code 128 barcode (All characters). The first linked field is alphanumeric and the second linked field is a five digit numeric field and the numeric field is incrementing. When the field increments past 99999, a function 4 is added into the field as the 4th. digit instead of just rolling over to 00000.

The subset code shift (from B to C) is being incremented.

Have the user set the Subset to B. This way there will be no code shift.
