Sorry to be a pain.
I've been looking at this this morning and it's really weird. I looked at the users profile this morning (the one I gave you) and that course was on there. After a few hours I looked again and it had disappeared again so I added it yet again. When I looked at the table orderoptions and searched for one particular course (ID 57) (that's the one we've been talking about) there were only two listed. Well I know that we have sold a lot more than that. It seems that somehow records are being deleted from the orderoptions table.
