Declined orders not deleted from database

[vickawicked]

If the order is declined by the gateway it still stays in the database.

 

Seems like the variable $insert_id is not passed any value:

 

if ($x_response_code != '1') {

tep_db_query("delete from " . TABLE_ORDERS . " where orders_id = '" . (int)$insert_id . "'"); //Remove order

 

 

Any ideas how this can be fixed?
