In every case except where the first candidate in the first contest was
selected. So, we pad with leading zeros to reach 116 digits. Is this what you
mean? Seems simple enough.

I don't see any problem with this scheme either. I should receive my
shipment of Cue Cat scanners tomorrow. Perhaps you could provide me with some
samples of barcodes in various lengths (say 15 - 40 symbols) that I can test with.
Can you post a .PDF file with several barcodes we can test with?
