thanks a lot for those quick replies.
you understood my problem right stolzyboy, the problem is the site's database being tied up close with the cinema's software for selling tickets, i don't think i can do that kind of connection to begin with.
i was thinking in putting some limits to this online reservation thing like:
1-people can only reserve seats in a specific area.
2-people can only make online reservations 'till a specific hour (the hour the box office of the theatre opens, that way the people down at the theatre can see what reservations have been made so they won't sell those tickets).
the problem comes to ticket selling for other dates and reservations for other dates, like buing/reserving a ticket for tomorrow.
what do you think?
