[Hustle Pro] Button with Hustle pop up

Hello, I created a custom button for our page http://www.nrsrentals.com/fl for the FL Rental Property Waitlist at the bottom of the page. The code I used is <div class=”wp-block-button”>FL Rental Property Waitlist</div> and the button was working to bring up the pop up hustle form but now it isn’t working. Can you please tell me what I may have done wrong here? Thank you so much
