How to add a class to avia layout editor element – part 2

I added this to my functions.php:

add_theme_support('avia_template_builder_custom_css');

Now, I see and can add classes to avia elements. I am having a problem getting easy modal to find the class and trigger a modal form to display.

The page is http://semba.bongo.cc/semba-octave-chromatography-systems/

There’s a table at the bottom of that page. I’ve added the class “eModal-2” to the 2 “Get A Quote” buttons at the bottom. I can see that the class is attached to a containing <div> around the button. That doesn’t seem to work, but –

On the home page http://semba.bongo.cc there is a promo box near the top of the page. I assigned a class of “eModal-1” to the promo box and that works!

Can’t figure our why the other buttons don’t trigger the modal form. Any ideas?
