Problems with Paypal Shopping Cart setup

[bukisan]

I set up an entire catalog of items and it all seemed fine until after I published the site. When you click on the add to cart or buy buttons another window opens with error messages. That information is missing. All the information for the items is in its proper place. I have not had this problem with 11. I am attaching the error messages. I am not sure what it is looking for.

Here is what is listed in the code for Add to Cart.
action.value=https://www.paypal.com/cgi-bin/webscr
action.target=paypal
action.method=post
parameter.input.hidden.cmd=_cart
parameter.input.hidden.business=<%store.email%>
parameter.input.hidden.item_name=<%product.name%>
parameter.input.hidden.item_number=<%product.sku%>

parameter.input.hidden.amount=<%product.price%>
parameter.input.hidden.shipping=<%product.shipping Cost%>

This code is listed in the configuration URLs. Still doesn't work. I don't understand why Paypal Store Engine still doesn't work.
