Check out Instant Web Publishing (IWP) and Custom Web Publishing (CWP) for two options for publishing your FileMaker database to the web.
could i press my luck and ask you to look at our current form?
do you think we would be able to get it looking anything like it?
Web publishing isn't something I have extensive experience with. I think you could probably do this with CWP, but it would take a bit of work to do and you may need to scare up someone who can use PHP to set it up for you.
