Editing the email contents in automated email notifications

I'm trying to setup a form to notify different email addresses based on the zip code entered in the form. The email notification needs to have the form data in the email body. I try to update the email notification with the HTML code below but it doesn't save.

Name: <%=Name%><div><br></div>Email: <%=Email%><div><br></div>Zip Code: <%=Zip_Code%><div><br></div>Phone: <%=Phone%><div><br></div>Contact Method: <%=Preferred_Method_of_Contact%><div><br></div>Service Needed:<%=Service_Needed%>
