Control digit configuration

Hi!

I have a barcode like that at the bottom of a label with these characteristics, and I have to put a number on the top of the label with only a part of the barcode number.

At the moment, it appears like this, but I only want the database number, the numerator and the control digit. I don't know why that incrusted data have to appear on first in order to appear the control digit.

Basically, I have it this way now on the barcode:

And that way on the number above:

If I eliminate the first incrusted data, the control digit disappears…

How could I put the number correctly? only with the database number, followed by the numerator and the at the end the control digit?

Thank you so much in advance!

  It sounds like you want to add a standard Code-28 barcode and not a GS1-128 variant as with the latter you must include the Application Identifiers (the 00 in your sample) and other control characters, where applicable.

  However, with the Code-128 you a UCC-Mod10 check digit will not be added as standard and so if you need this then you would need to use VB to create it. In the image below I named the rest of the barcode data “TheDate” so I could reference it more easily in the VB
