How do I change what page users are directed to when they click "Apply Now" on our current job openings page?

I created a new application for 2014 that we want to begin using on our website, but I cannot figure out how to change the "Apply Now" button to direct our guests to this new application. Where would I enter this information? The apply now button is still set to direct people to our old application right now.
