In the following code to prevent people from using the back button to steal:

PHP Code:

// ################ to prevent repeated attempts #################
if ($action=="stealverify") {
$getrobber=$DB_site->query_first("SELECT storep FROM user WHERE userid='$bbuserinfo[userid]'");
If ($getrobber[storep]<0) {
    eval("standarderror(\"".gettemplate('store_steal_cannot')."\");");
}
$getduser=$DB_site->query_first("SELECT userid,usertitle,username,storep FROM user WHERE username='".addslashes(htmlspecialchars($stealusername))."'");
$contest = $DB_site->query_first("SELECT * FROM store WHERE action='steal'");
$storeid=$contest[id]; 


There is NO change for me when I use this code above, as opposed the the original code of:

PHP Code:

if ($action=="stealverify") {
$getduser=$DB_site->query_first("SELECT userid,usertitle,username,storep FROM user WHERE username='".addslashes(htmlspecialchars($stealusername))."'");
$contest = $DB_site->query_first("SELECT * FROM store WHERE action='steal'");
$storeid=$contest[id]; 


Can you help?
