Can you help me please? I have installed the Store module and set up the payment settings for PayPal and when I complete the billing details in the shopping cart and click on PayPal Pay now button it gives me an error as follows.....

We cannot process this transaction because there is a problem with the PayPal email address supplied by the seller. Please contact the seller to resolve the problem. If this payment is for an eBay listing, you can contact the seller via the "Ask Seller a Question" link on the listing page. When you have the correct email address, payment can be made at www.paypal.com.

I have been in touch with PayPal and their response is as follows:

I have gone to your Web site and attempted to place a test order. Based on what I am seeing, it appears that the Web site is making the correct correlation to your PayPal account. As your site is using a script to transmit the information to PayPal, I am unable to see exactly what is being submitted.

I have triple checked my email contacts with PayPal and with no luck.

Thanks!
