Your problem is in the ajax.js file. you are executing the check function before the ajax call is made.

Change:

if (isFirefox() && firefoxVersion() >= 3) {
    httpReq.onload = check(div);
} else {
    httpReq.onreadystatechange = check(div);
}

to:

if (isFirefox() && firefoxVersion() >= 3) {
    httpReq.onload = function(){check(div);};
} else {
    httpReq.onreadystatechange = function(){check(div);};
}

Also, Please look into Sql Injection. At the very least you should not be passing the SQL queries in the url.
