Sorry, I mistakenly said document when I really meant to say template. The code was from the invoice.zip file. I just copied it and pasted it into my new "template".
I tried just adding content to the invoice.zip, it just moved the numbers around. Once I added anything to it it would not work anymore. The other things list above, I do not know how to do those things. It seems to me that invoice auto numbering should be a simple task, but it is not for me. I can continue the way I have been doing it for about 3 years now, but it would make it a little bit easier if I could figure this out. Thanks
