i know i have done the first part correctly because i get the 'congratz' message, however
when i go 'back' and clear the log files all i get is 'you have cleared the logs but you havn't transferred any money'

could this have something to do with the POST data been re-posted when i click 'back'?
i have been using the Firebug plugin to alter the necessary data for clearing the logs.
can anyone shed any light on what is going wrong here?
