What is wrong with this ?

Hello,I'm working an a google maps API V3 and using AJAX to get data from an XML. Every thing works fine and i get all the data properly. The problem happens when i attach a variable to the XML link.Here is the map :http://69.167.189.144/~meshalw/g/indexg.phpPlease check the page with Firebug.When it first loads from the XML (with no variables attached) it works fine. However, try to insert an input and submit, Firebug will show the link with RED and it wont bring any thing.I find it strange that if you copy the red link that Firebug shows, and go it through your explorer than it will show you the result without problem. (e.x : http://69.167.189.144/~meshalw/g/xml.php?rooms=6 )I'm a newbie on this and have spent 2 days trying to fix this !Any help will be appreciated. Thanks
