Dave I really appreciate the reply.
I would like a Web Assist tech to repsond if possible and tell me what's wrong with the current page. I could add another page if it was absolutely the only solution, but the checkout process is already many pages long, I really don't want to add another one.
Does anyone know what it is that actually causes this problem?
To me, it is very strange that all the other pages work fine and just a couple of them display this error ... what causes it?
