Copy and pasting the recordset will work as long as you aren't trying to directly refer to the first recordset value in a parameter. You would need to store the parameter as a $_GET variable for instance temporarily to get around that problem. The tech guy rightly didn't want to walk you through it and debug it with you, but I assure you it is possible. His mixed results were probably as a result of users mixed abilities in following his instructions.

What checkout provider and shipping providers are you using? It is likely you will need to cut and paste code into a particular location to get those working properly on GoDaddy. You should probably post a support incident when you are ready to go live including that information and they will guide you through the necessary updates.
