Yes I'm comfortable with the reasons, and already found the code sending
the false headers. I'm aware of the problem but I dont have a lot of
experience with ecommerce sites. This one will be a first complete job.
I wanted to give PHP a try and looked at a few cart scripts. FreeTrade
seems to have slotted in OK!

I havent checked Amazon. Its probably a good place to look!

Without discussing it with my client, I dont think I need to support
mulitple addresses, so blockign multiple adds may be a way to go. I
havent really been thru the code in there yet tho.

I had a mind that I might include a javascript history-1 back link
somewhere so I dont want to take this route just yet.
Anyway, its 2:30am here so I'm gonna think about it again tomorrow.
No doubt I'll be back here again soon!
thanks again
