Writing to an SWF

Huge apologies for having posted this twice (it's also in 'General Help') but I'm not quite sure where it should be???

THE PROBLEM
Hi, this is driving me crazy and I'm afraid I don't even where to start looking (or even how best to ask) for help. What I'd like to be able to produce is the following:

'User-bookable time slots' (or however else they might otherwsise or more appropriately be termed).

I'd like to create a table indicating time slots (10am til 11 am; 11am til 12; 12pm til 1pm etc) which, if not already taken - i.e. someone else's name isn't already displayed in a slot - will allow the user to type his/her name in, then hit a submit button whereupon the his/her name will be shown in the slot rendering it unavailable to subsequent site users.

Does any of this make sense? I'm having trouble getting my head 'round how to achieve it, despite having successfully added guestbooks and all manner of other 'read/write' sort of stuff to various of my sites.

Sigh... I think I might be having a 'senior moment'! Please, please help!!!

Many thanks,
Fran

can you show us what you already have i.e to what stage have you completed it. cheers..

Thanks, but I've only really got an image that I could sling up at the mo' as I've essentially been trying to work out the bump and grind scripting side of things before I built it all (to save time in case it can't be achieved).

I can put up a pic of how it 'could' look if that's a help?
