Unavailable HTML elements are used in the form template.

I just installed the Theme “Bookshelf” which comes with Contact Form. It says there is one error in this form. This is the code. Does someone know whats wrong with it?

<div class=”sc_contact_form sc_contact_form_standard aligncenter”>
<form class=”inited”>
<div class=”sc_contact_form_info”>
<div class=”sc_contact_form_item sc_contact_form_field label_over”>
[text* your-name placeholder “Name *”]
</div>
<div class=”sc_contact_form_item sc_contact_form_field label_over”>
[email* your-email placeholder “E-mail *”]
</div>
<div class=”sc_contact_form_item sc_contact_form_field label_over”>
[text your-subject placeholder "Subject"]
</div>
</div>
<div class=”sc_contact_form_item sc_contact_form_message label_over”>
[textarea your-message placeholder “Message”]
</div>
<div class=”sc_contact_form_item sc_contact_form_button”>
