Why are you using the discount field for the reason? There is something made for things like this.

This:

PHP Code:

    uttstore_add_history($action['actionid'], $action['cost'], $reason, $action['tax'], $totalcost, $_REQUEST['userid'], $_FIELDS['points']); 


Can become this:

PHP Code:

    uttstore_add_history($action['actionid'], $action['cost'], $userdiscount, $action['tax'], $totalcost, $_REQUEST['userid'], $_FIELDS['points'], $reason);
