Jump menu problem

[ayok]

Hi, I make a jump menu with the options based on mysql database.

The jump menu is working, however, when it gets to the selected page, the "selected" option is back to the first page.

This is my try:

$payment = mysql_query("select * from payment") or die(mysql_error());
echo"<select name=\"pay\" onchange=\"MM_jumpMenu('parent',this,0)\">
          <option value=''>Select method</option>";
$amount = $_GET['pay'];
while($pay = mysql_fetch_array($payment)){
	echo "<option value=cart.php?pay=$pay[pay_id]";
	if(!(strcmp("cart.php?pay=$pay[pay_id]",$_GET['pay']))){ 
		echo "selected";
	}
	echo ">$pay[type]</option>";
}
echo "</select>

So everytime it jumps to the other pages, the selection always back to "Select method" option.

What should I do to make the selection stay in each option selected?

 

Thank you,
