Submit button not working

My send message button is not activated for some reason. It won’t even load like it doesn’t have any action set to it.
this is form for contact us:
<h2 class=”short”>Contact Us</h2>
<div class=”row”>
<div class=”col-lg-6″>
<div class=”form-group”>
<label for=”contact-name”>Your name *</label>
[text* your-name id:contact-name class:form-control]
</div>
</div>
<div class=”col-lg-6″>
<div class=”form-group”>
<label for=”contact-email”>Your email address *</label>
[email* your-email id:contact-email class:form-control]
</div>
</div>
<div class=”col-lg-12″>
<div class=”form-group”>
<label for=”contact-subject”>Subject</label>
[text your-subject id:contact-subject class:form-control]
</div>
</div>
<div class=”col-lg-12″>
<div class=”form-group”>
