Empty variables if browser back is used?

[wudz]

Hi,

Just found a bug and I am unsure of the answer.
I have a Select page with three radio buttons the page also has a menu choice.

If I choose a radio button and select a menu then submit all is well if the page is selected from the home page.

The problem is if the back button is used and another button choice is made on submit the button variables passed always resort back to the button 1 variable.

The menu is not really any problem even though it retains the past selection.

How can I clear the button if browser back is used even though the button does shows a different choice, it's attached variable is not picked up.

Cheers in anticipation
John

Sorry forgot to show the code used,,,

HTML

<A NAME=goto></A>
<FORM NAME=catform ACTION="<?=$_SERVER['PHP_SELF']?>#goto" METHOD="post">
<INPUT TYPE=HIDDEN NAME="action" VALUE="process">
<INPUT TYPE=HIDDEN NAME="box" VALUE="">

<tr>

<td width="40%" height="5" align = "center" BGCOLOR="#ccff33">
<INPUT TYPE=radio NAME=auctiontype VALUE="3" <? print $TPL_standard; ?>>
</td>


<td width="20%" height="5" align = "center" BGCOLOR="#ccff33">
<INPUT TYPE=radio NAME=auctiontype VALUE="2" <? print $TPL_dutch; ?>>
</td>


<td width="40%" height="5" align = "center" BGCOLOR="#ccff33">
<INPUT TYPE=radio NAME=auctiontype VALUE="4" <? print $TPL_classified; ?>>
</td>



PHP

// -------------------------------------- Select Auction type
if ( intval($auctiontype)==3 ) $TPL_standard = "CHECKED";
if ( intval($auctiontype)==2 ) $TPL_dutch = "CHECKED";
if ( intval($auctiontype)==4 ) $TPL_classified = "CHECKED";

$_SESSION["auction_type"] = $auctiontype;




if($_POST['action'] == 'process' && (intval($_SESSION["auction_type"]) <1 )) {
$TPL_error_text = $ERR_117b;
$sessionVars["returned"]= 'r';
Header("Location: select_category.php?mode=recall");


cheers
