Draw on Map

I recently updated a client’s website from one theme to another. The previous theme they used was called CleanIDX. Anyway, for some reason, when I updated the theme virtually everything remained the same… except the “Draw On Map” tab from this shortcode [optima_express_basic_search] no longer works. I click it, and it nothing happens.

The only thing I can say is when I scroll down a bit and try to click it, it makes the page scroll up a little bit, but other than that – nothing.

Can you provide some help with this? http://www.bardellrealestate.com/search-homes-for-sale-in-orlando-2/
