Answer 1

<input type="button" name="send" value="Send Response">
Type needs to be submit unless you have a separate event handler in your Javascript to send the data.
<input type="submit" name="send" value="Send Response">
Otherwise no event is fired except the mouse clickies.
And yeah your PHP needs $_POST not $_post but that's not really what's affecting the send button being unresponsive.

Answer 2

Basic PHP 101: Variable names are case sensitive
if (isset($_post['send'])) {
^^^^^--- undefined variable
It should be $_POST. If you had display_errors and error_reporting turned on, you'd have been warned about using an undefined variable, and treating that undefined variable as an array. The debug options should never be off on a devel/debug system in the first place.

Answer 3

You have not closed your else condition
at the end of the file close the else tag
</form>
<?php }
