We're going to need more info, because I don't know how 'simple' you want it
to be. Databasing & dynamic content can be quite complex.
1) What version of FP do you use
2) What server type are you publishing to (Linux/Windows 2000/Windows Server
2003 etc)
3) What server side scripting technologies are supported by your host?
4) Are you familiar with 3) above such as ASP, Perl/CGI or PHP?
5) For the sake of simplicity try
www.ezscripting.com; simple scripts
(relatively) with comprehensive instructions and a help forum. Uses flat
text file database (text files, character delimited). Can be applied to
whatever kind of site you want The site features demos of all the
scripts - it is best to view the demos to get an idea of the features.
Another suggestion, search "Real Estate Listing" (and similar keywords) on
www.hotscripts.com (this is just one site I visit often, so it is a good
starting place).
Search for a script in each of the script type categories (whichever is
supported by your host - check with them first).
Note, whatever you end up with, it will require server side scripting of
some sort.
