Solved: Is this possible or am I on drugs :)

Thanks for everyone's responses :)

It seems I simply wasn't able to explain what I was trying to do.  I knew
how to do this with PHP already.

On the bright side I've decided to do things the way you think I'm doing
them, rather than the way I was thinking of doing them :)  How's that for
cryptic? :)

I'll end this thread now and not confuse the list with my rambling
thoughts for the imediate future. :)

Thanks once again for all the reponses.
