PayPal Buttons

When I dump my PayPal button URL into our Pack information/landing page for paying dues it shows up as a link. When you click on the landing page button that was just created it takes you to a separate page with the PayPal button and payment drop down options correctly. When you click on the Pay Now button once selecting a payment option value nothing happens.

Am I doing something wrong?

Why doe it not take you to the PayPal payment/checkout page?

Any help would be greatly appreciated.
