What is a solution for the contact form button not working?

My email is entered in the contact form and clients are filling it out and I’m not receiving the information they enter on the form.

Here is the link to the page: http://bodymindlinks.com/book-a-session/

Here is everything that is in the quick CSS:
.main_color {
background-color: #ffffff;
}

.socialize-containter { display: none !important; }

.avia_ajax_form .button { margin-right: 20px; }

body.page-id-180 .template-page.content {
padding-top: 0;
}

.footer_color a { color: white; }

.main_color input[type=’submit’] {
background-color: yellow;
color: blue;
border-color: yellow;
}
.main_color input[type=’submit’]:hover {
background-color: yellow;
color: blue;
border-color: yellow;
}
