url parameter reset?

[han_u_man]

I can take a url parameter primary key from page one to page two.(eg
....?order_id=7)

Taking a different key from page two to page three or returning the key back
to page one the orginal url parameter is still on the address line and confuses
the browser. (eg ?order_id=?order_id=7)

I have looked at the code and it seems to be passing the correct parameter

Is there anyway to reset the url parameter in Dreamweaver ?
It is to do with my browser (firefox 1.0)?

Using php mysql
Below is code generated by update record field

$updateGoTo = "invoice_filler.php?invoice_id=" .
$row_rsSubinvoice['invoice_id'] . "";
if (isset($_SERVER['QUERY_STRING'])) {
$updateGoTo .= (strpos($updateGoTo, '?')) ? "&" : "?";
$updateGoTo .= $_SERVER['QUERY_STRING'];
}
header(sprintf("Location: %s", $updateGoTo));
