Many thxs for the info, but now I’m in shock
I was very close to completing the shopping cart, so I was shocked to hear that it does not work correctly now!
Could you please advise on the code to update the checkout.php page?
I think the way forward is to re-design the checkout page to only have two buttons to choose from.....Paypal & the Authorize.net processing button. Everything else Billing Info, Delivery Info & check-out button at the bottom of the page should be deleted. We can look at the process for Authorize.net later, as you say.
With regard to the Paypal sequence could you please advise on what code I need to replace/delete for Paypal to process all & only come back to my website showing the checkout success page!
Also with regard to the invoice number where is this code located?
Please see part of the relevant check-out page code attached
