                //when the mouse is over a star, we want to change all the stars below to selected stars
                function oMOver(starNum){
                    //replace stars
                    i=1;
                    while(document.getElementById(i) != null){
                        if(i <= starNum){
                            document.getElementById(i).style.backgroundImage ="url(/images/taken_star.png)";
                        }
                        else{
                            document.getElementById(i).style.backgroundImage ="url(/images/free_star.png)";
                        }
                    i++;

                    document.getElementById("rate_widget").lastChild.innerHTML = messg[starNum];
                }
 
            //1.1

                function oMOut(actualRate, numRatings){
                    i=1;
                    while(document.getElementById(i) != null){
                        if(i <= actualRate){
                            document.getElementById(i).style.backgroundImage ="url(/images/taken_star.png)";
                        }
                        else{

                function oCKStateChange(){
                    if(objectXHR.readyState == 4){
                        if(objectXHR.status == 200){
 
                            //store result
                            rWResponse = objectXHR.responseText;
                            window.document.getElementById("rate_widget").innerHTML = rWResponse;
                        }
                    }
                    else{
                    }
                }
 
                function oCK(starNum){
                    var rateSentParameters= "rate="+starNum;
                    objectXHR.open("post","../rate.php", true);
                    objectXHR.onreadystatechange = oCKStateChange;
                    objectXHR.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
                    objectXHR.send(rateSentParameters);
                }
