How do I add a secure paypal button?

How do I add a secure paypal button on http://www.musicandmedianetwork.com/?event=2014-inspiration-symposium-4 in place of the one at the bottom of the form there now? I am using Events Manager Pro which creates a form with a button at the bottom, when I enable booking(it is not enabled now, so you won't see it there), but that button is not secure.
