Hi Stephanie,
I had a look at your page and the layers were a bit off. I don't know if you're familiar with how a page is built, but there was basically an invisible layer over your buttons, which usually sits on the "bottom" of the page. You can think of layers as pieces of glass. Layer zero is your screen, and each layer up gets closer to you as you are in front of the screen.
I've updated the layers in your form, setting the buttons to the highest layer so there is nothing blocking them, and they are working as expected now.
Please let me know if there is anything else I can do.
John
