How to remove the payment tool?

im trying to add paypal as my payment tool, but its telling me that one is already selected.

You can only have 1 payment tool on a single form. I cloned your form and I can see the existing payment method. You need to delete this first in order to create a new one.

If you want to have a multiple payment tool in a single form, then please refer to this guide: How-to-Create-a-Basic-Multiple-Payment-form.

Hope that helps. Thank you.
