I have a very simple shopping cart on my website. I'm only selling one item but you can add a quantity of the item to your cart. The final price will and can differ for each customer. I want to add a Pay Now / Buy Now button to the end of the shopping cart that picks up of the price in the shopping cart, and when you press the PayPal button, it re-directs you to pay with PayPal with the right amount from the cart. I tried creating a simple Buy Now / Pay Now button and adding this line (<input type="hidden" name="amount" value="<?= number_format($discountedPrice, 2); ?>">) to it but no joy. I looked at the PayPal Developer portal but I'm not the best coder and wasn't sure what to do. Can someone help point me in the right direction please.
