<?php
session_start();
if(isset($_SESSION['MSG'])){
echo '<div  id="incorrect">' . $_SESSION['MSG'] .  '</div><script 
type="text/javascript">  
function showIt() {  
document.getElementById("incorrect").style.visibility = "hidden";

Try this

if(isset($_SESSION['MSG'])){
    echo '<div id="incorrect">'.$_SESSION['MSG'].'</div><script type="text/javascript">
    document.getElementById("incorrect").style.cssText = "background: red";
    function showIt() {
        document.getElementById("incorrect").style.visibility = "hidden";  
    }
    setTimeout("showIt()", 5000);
    function showIt() {
        document.getElementById("incorrect").style.cssText = "background: yellow";
        document.getElementById("incorrect").style.visibility = "visible";
        document.getElementById("incorrect").innerHTML = "'.$_SESSION["try"].'";
    }
    </script>';
}

You use the innerHTML to change the message within the <div></div>.
