Hi, @Stony778. Thanks for adding your question here on the PayPal Community Forum. I'm sorry for any inconvenience, but the approach you described is not possible for a PayPal transaction.
A purchase has to be funded by one payment method unless there is money in your PayPal account balance. In some cases, if money in a balance is not sufficient to cover a purchase, the remaining amount may be taken from a bank account or card. It's not possible, though to use money from two different cards or a bank account and a card to pay for a purchase.
Beyond that as well, it's not recommended to add a gift card to your PayPal account since it might not work (compatibility issues), the Security System might not allow it to be used for the desired purchase, and there would likely be difficulty returning money to the gift card if a refund needed to be issued.
