Okay, you've got a number of threads in this conversation which have details you haven't had a chance to look into, so I'm going to let you do that and stop spamming you with ideas.

I am going to take your code, tweak it to use at my web site, and build a site to mirror your efforts.

Assuming it works on my site, I'll start adding debugging features which I can then ship back to you to try.

I suspect I'm going to feel really silly about something basic we've overlooked when this is all said and done.

See you in a bit.
