The button to add a pledge after a goal is underway seems to be totally nonfunctional.

I want to add a pledge, but when I click the "pledge $5" button above the graph, it just takes me straight to the page for updating my CC info. I have an up-to-date credit card on file already. I tried updating up but nothing changed.

I tested this 6/17/14 in both Chrome and Firefox. the button does nothing except take me to the payment settings page.
