I need a PDF file that everytime it is opened will have a successive invoice number at the top of the document. In addition, the invoice number needs to be in synch with 3-4 other PDF files. In other words, if someone opens [url removed, login to view] and the invoice number is "101" and a split second later someone else opens [url removed, login to view] the invoice number at the top of the document is now "102".
I need a minimum level of security with this project (so the invoice number can not be manipulated... either on purpose or accident)
