simple ajax problem, help

Hi, i did a php tool and i want to show the results with ajax.
Here i have a part of ajax code :

   function get(obj) {
      var poststr = "mytextarea1=" + escape(encodeURI( document.getElementById("results").value )) +
                    "&mytextarea2=" + escape(encodeURI( document.getElementById("extension").value )) +
                    "&mytextarea3=" + escape(encodeURI( document.getElementById("no").value )) +
                    "&mytextarea4=" + escape(encodeURI( document.getElementById("kind").value )) +
                    "&mytextarea5=" + escape(encodeURI( document.getElementById("cv").value ));
      makePOSTRequest('do.php', poststr);
   }

Code (markup):

a php code :

results id is <input> and extension is <select>, when i run the form it shows me only $_POST['results'] variable.
I think the problem it's on ajax, maybe i wrong ids definition.
Please help me.
