PHP Parse error: syntax error, unexpected T_STRING in D:\Hosting\???????\html\includes\languages\english\email_extras.php on line 31

I forgot to add a colon, (enter extreme laughter here), at the end of that php code and had NO IDEA that a mis-edit of that file would take down my entire store front.

Thank you DrBytes.
