Hi, I'm creating a form for my business. I want an invoice number on each form for it to rise by 1, so that we can save each form and easily find old ones etc. I have some programming experience but honestly no idea where to start with this.
The form will be a pdf and I'd like it to be able to be hosted online so that multiple computers (both windows and mac) primarily running Reader can open it, with the form counter going up by 1 for each form.?
You can't use (just) JS for this. You need a server-side script to keep track of the invoice numbers and populate a new one into the PDF each time it is opened by a user. Not a trivial task...
