the order number field is either 5 or 6 characters, some have a letter and 5 digits but the dupes are all just 5 characters, always numeric, always in the same place. There are various amounts of dupes. Looks like from 1-3. To let you get a better understanding. The order# field is our job number, and the keywords field is the invoice number associated with the job. Some jobs receive more than one invoice.
