Contact Form Not Sending Messages

Hi guys,
I’m using OneTone Theme that comes with a supplied Contact Form on the homepage. I’ve been testing and testing it to no avail. I’m not receiving anything. I’ve tried to switch the supplied code to “mailto:…” and taking that bit out. Still, nothing. Could you brilliant people help me out?

Here is the code it supplied:
<div class=”contact-area”><form class=”contact-form” action=”” method=”post”>
<input id=”name” tabindex=”1″ name=”name” size=”22″ type=”text” value=”” placeholder=”Name” />
<input id=”email” tabindex=”2″ name=”email” size=”22″ type=”text” value=”” placeholder=”Email” />
<textarea id=”message” tabindex=”4″ cols=”39″ name=”message” rows=”7″ placeholder=”Message”></textarea>
<input id=”sendto” name=”sendto” type=”hidden” value=”[email protected]” />
<input id=”submit” name=”submit” type=”button” value=”Send” /></form></div>

What am I doing wrong?

Thanks so much! ??
