Last name not submitting to PayPal
I've checked other posts on this subject and tried different versions of coding but still can't get the last name to submit correctly to PayPal - although I can get it to go to the first name box (instead of the first name). All of the other details submit correctly.
I don't quite understand why the Name is a single field in the PayPal Authentication Express Checkout server behaviour when first and last names are separate fields on the checkout form as well as PayPal's page, as this seems to be what creates the problem? And I can't see how or where to change this or what other problems that might cause.
So, here is what appears to be the applicable existing code from confirm.php:
$nextIndex = count($WA_PP_ECO_Set_params);
$WA_PP_ECO_Set_params[$nextIndex] = "Name";
$WA_PP_ECO_Set_params[$nextIndex] = "".(WA_getSavedFormValue("CheckoutWizard_Cool_nzanlp","First_Name")) ."";
Would you please advise what I need to change to make this work?
