150766 Script Repair

Hi There I have a well established Traffic Exchange website and I need some work done on my script. There are a few problems that need sorting and I do not have the time to take a look at them hence I advertising here. On the sign up page there seems to be a problem, also some members have been complaining that there credits in there account are going missing from there account there must be a bug somewhere in the script what needs ironing out. I need some one to take a full look at the script and fix ALL bugs that are there maybe with a few upgrades put in place. Domain name will be given to winning bidder. Regards Anthony
