URGENT : PHP SCRIPT HELP

We have set up the google checkout PHP API to notify us of payments and it is doing exactly what it is supposed to do. We also have a new database class set up to send this information to a mysql database. For some reason there is an error somewhere in the script which is stopping it from doing so. Should take 15-30 minutes max to finish if you are an expert with php please only bid if you have msn/windows live messenger
