Help in altering a template - how to remove credit card fields from order element

I'd like to remove the credit card information portion of this form that I found in your templates and replace with a link to my payment portal.  Possible?

You may remove the current payment field from your form (the current products will be safe):

And then add a Purchase Order field from the Payments tab:

The Purchase Order field offers the same layout and does not require online payment.

An HTML link can be added with a Text element. This is also possible to redirect a user to the custom URL upon the form submission.

Every time I hit the delete button, the entire thing goes away, including the tshirt information and images.  How do I make JUST the credit card part go away?

Yes, the whole payment field, products included, will be removed when you delete the existing payment field on your form. However, when you add the Purchase Order, which is also a payment field, the products should be restored automatically without the credit card fields.
