Hey Vinyl Signs,

There appears to be a break in the source code.

You could file compare a stock zen cart install with the following folders:
admin/includes/languages/english/email_extras.php
email/
includes/languages/english/YOUR_TEMPLATE/email_extras.php

Let me know if you need more direction or any assistance. I have made a module that replaces the stock Zen Cart email folder and updates email text to improve functionality and compatibility with a newer broad range of devices.
