Incorrect Custom Check Digit

Legacy Poster

Hello, 

I used the C39Mod43 function to create the custom check digit for a 2D Data Matrix. The check digit appears as expected on the code and the human readable content (Value = 7) but when I print, the custom check digit value changes to a different character. (I get "P" instead of the number "7")
Why does the value change when I print? I also used a event based script but it didn't work. Kindly help.

  It appears that half of the data in the overall string is blank at print time.

   

  If you look at the attached picture.  The upper string is the concatenated data source at print time - basically your VB script expression without the check digit function.  The lower string is the same concatenated VB script as it displays at print time.

   

  Maybe try using an Event based VB script and use the OnIdenticalCopies event for the expression.
