Eric,
Thanks for the reply. And I will follow up on your recommendations. A couple of details, and questions first.
Will creating the new checkout page affect what I have already? I ask because I have some stuff working. What I did was first, hide/ignore the PayPal Express button that appears at the top of the checkout.php page. And then, I changed the value of the form button "Checkout" at the bottom of the page to my test email address. This seemed to fix the error.
So now I go from;
Main product page with (add to cart button)
then to the cart.php page which has my details, price & shipping
then if I click on "Checkout" it goes to the checkout.php page to fill in addresses.
then if I click on the bottom button it goes to the confirm page.
and finally, if I click on "Checkout" it takes me to PayPal with all details filled in.
Here's where I get confused. It wants me (as the buyer) to login or create an account.
Since it's my understanding that PayPal Standard does not require an account for the buyer, then I might have something wrong here. Maybe creating the new page you mentioned will fix this, but I wonder if I would end up with the same result by deleting the Express portion.
I will remove my personal information and post the pages. But for now I wanted to update what I had done. And also post a screen shot of the page in question. The two buttons I referred to in my previous post are visible here. These were both created at the same time, within the Checkout Wizard, but they behaved differently.
Thanks,
TroyD
