Ok, now this part is working and confirm page displays but when I press submit button on pp_confirm.php a failure page appears with this message (I removed password and user ID and some other things)
"Your PayPal transaction could not be completed. pp_cancel.phpSoleBillingAuthorization0.110.10.01test 0.113Authorization2012-05-29T23:58:45ZSuccess2ad686afcc72e63WebAssist.eCartPHP.Pro.ECOtest 0.1132012-05-30T00:06:23ZFailure39327bc8e59afExpress Checkout PayerID is missing.Express Checkout PayerID is missing.10419ErrorTransaction refused because of an invalid argument.

Also the billing info at bottom is blank.
