friends, I wonder if you can offer any advice ?

My client wants to run his site as follows ( for now )

- customer browses site, fills cart with products

- goes to checkout submits order but no payment

- client phones cutomer to complete transaction over the phone ( he takes phone orders already )

I have got most of the way towards this but when I click "confirm order" nothing seems to happen, it just goes back to the home page and no order comes through.

Any ideas ?

TIA :)
