Hmmm.. thank you so much for your replies :) I've done some thinking - wow - and I think I will skip the "auto-generate pdf" part of this... The customer must fill in some information manually anyways, so I might just as well make a "default" pdf, and make that one available to all customers... I don't want to spend too much on this as I don't think the gain would be big enough for the customers to justify the work needed to get it working.. But I am absolutely not sure either... So I guess I will think a little - more - about this.. and I will most likely come back on this...

Anyways, thanks for you replies - and it has been of great help.. sometimes it helps just to write things out loud ;)
