Hi, I have a function that returns the correct update: 
 
function updateCart() { 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if((isset($_POST['update'])) &amp;&amp;&nbsp;(isset($_POST['qty'])) &amp;&amp;&nbsp;(isset($_POST['item']))) { 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$item = trim(mysql_clean_strings($_POST['item'])); 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$qty = trim(mysql_clean_strings($_POST['qty'])); 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$cart = $_SESSION['cart']; 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$_SESSION['cart'][$item] = $qty; 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var_dump($qty); 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return $qty; 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} 
} 
 
but it doesn't show the update till the next time (either enter a new quantity or click refresh). &nbsp;How can I make it show the changes on the first click (submit) ? 
 
You will need to add something first:

Why does my page need to be refreshed to show the shopping cart update?
