HTML code

Hi I edit my html code as this:
<p class=’comment-form-subscriptions’ style=’margin-bottom: 40px;’><label for=’subscribe-reloaded’><input style=’width:30px’ type=’checkbox’ name=’subscribe-reloaded’ id=’subscribe-reloaded’ value=’replies’ checked=’checked’ /> Mandami una notifica quando il mio commento riceve una risposta.</label></p>

But this code don’t works because is show the preset code.
How I have to do?
Thanks
