What are you trying to sell in the first place? If you are selling digital products or services, just use Sellfy. Your website builder should also prompt you about what kind of website you are creating before you start, and an online store should be one of them.

Payment gateway?

Thread moved to internet talk subsection , it's off topic.
I do believe paypal offers a payment button but you could also add an image that is also a hyperlink to a paypal address or something, what are you trying to do exactly? sell actual items from a list? Id just like more details on what you are doing, what services you are using ie paypal or something else like westernunion to wire money.

I already fixed this a while ago lol

Well OPs problem is solved closed.
