Ok i'll start from the top~

Well when i first got the store up and running it is fine it reads the SQL perfectly, the problem i'm having is its NOT able to do chargeback properly however normal charges works fine, there seems to be something wrong with the actual system, i am looking for help here, also i will attach the Files needed to modify please please help me

~ So what it is thats bugged i believe is functions.php not sure cause i'm not a php coder...many thanks if you can work it out~
