[Plugin: Gravity Forms Popup Widget] Can't get popup form to work on button click

Here is my page: https://standoutonline.ca/~ryza/healthy-lifestyle/ask-a-dietitian

I’m trying to get the form to pop up when the ‘ask our dietitian now’ button is clicked. I can only get it to work on page load…. any advice?
