Hi all, This is a long shot but I'm still giving it a try. We are needing to send an email to a few hundread of customers announcing some sort of promo; they would receive a link which should go to our website and generate a pdf with a random barcode or just a long number on it which we also need to keep track of, that is, we need to know which barcodes or numbers are being generated and "assigned" to each customer as then when they use their printed pdf to redeem the object of the promo we can be sure that each customer only uses the code once. So, this is kind of two or three questions in one: * Need to generate random code and pasted it in a document. * Keep a list of generated codes. * Create the pdf for the customer to make a hardcopy of the document. So, I know this might not be the adecuate list to ask this but I really dont know a better list to ask to! Thanks in advance!
