mysql database is not working properly

my website [login to view URL] is currently not functioning properly. it used to work just fine before someone messed with it. if you go here: [login to view URL] and click on one of the detailed properties, it should pull up a new screen and show you the property details. i have another site that is working just fine that's exactly the same thing: [login to view URL] here is the page again like the one above: [login to view URL] now if you click on one of the property details it will come up: example: [login to view URL] will you need a username and password to view: username: michael at [login to view URL] password: mike this uses mysql and for some reason not all properties are showing. this is what i need corrected. all properties being shown. please help.
