Specific email conditional on Radio Button selected in Form

Question

Thank you for all the info here, but I seem to be missing something to make it send to each particular email address.

Basis for this code came from thread: Send PHP Form to Different Emails Based on Radio Buttons

<form name="contact-form" method="post" action="contact.php">
  <div class="form_details">
    <input type="text" id="field_name" name="sender_name" class="text" value="name">
    <input type="text" id="field_email" name="sender_email" class="text" value="email" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Email';}">                                     
    <input type="text" id="field_subject" name="sender_subject" class="text" value="subject" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Subject';}">                                     
    <textarea id="field_message" name="sender_message" value="Message" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Message';}"></textarea>
    <div class="clearfix"> </div>
    <div class="sub-button">
      <div style="float:left">
        <input type="radio" name="department" value="archery"> Archery
        <input type="radio" name="department" value="firearms"> Firearms
        <input type="radio" name="department" value="general"> General Inquiry
      </div>
    <div class="g-recaptcha" data-sitekey="6LeydxcTAAAAACBd4beoLDgtu0LIqzTWOJnvfsH-"></div>
      <input type="submit" name="send_message" value="Submit">

  </div>
</form>

  $subject = 'SC Website Message ';     

  // Construct email body     
  $body_message .= 'From: ' . $name . "\r\n";     
  $body_message .= 'E-mail: ' . $mail_from . "\r\n";
  $body_message .= 'Subject: ' . $sender_subject . "\r\n";     
  $body_message .= 'Message: ' . $message;     

  // Construct email headers     
  $headers = 'From: ' . $mail_from . "\r\n";     
  $headers .= 'Reply-To: ' . $mail_from . "\r\n";     

  $mail_sent = mail($mail_to, $subject, $body_message, $headers);     
  if ($mail_sent == true){ ?>         
    <script language="javascript" type="text/javascript">         
      alert('Thank you for your message, we will be in contact shortly.');         
      window.location = 'contact.html';         
    </script>     
  <?php } else { ?>     
    <script language="javascript" type="text/javascript">         
      alert('Message not sent. Please, notify the site administrator     [email protected]');
