thanks for your reply tommy
unfortunately your suggestion doesnt work (also requiring two click)
I think because of the following line
if(isset($_POST['Submit'])){
i suspect the problem with your solution is that $_POST['Submit'] isnt set
until it is clicked (i think).
i need the isset function to eliminate the problem of the sessions being
changed during other events that occur on this page.
