Thank you for your help, Ray. With your assistance, I was able to get everything working now. However, I have two separate issues, now. These issues are as followed:
1. The checkout.php does not have an type of check to see if any fields are left blank. One can literally leave the entire form blank and proceed to check out. Is there a simple, snippet of code I can add to the .php file, or should I run through the checkout wizard?
2. No email confirmation is sent to the customer.
Any and all help is greatly appreciated. Thank you for your time.
