How can I duplicate the order summary email

I used checkout wizard to produce pages.
I have 'confirm.php' page that has button when clicked sends email order to client.
I want to have another button which sends very similar email, but with different wording.

I have created a button.
I duplicated the email file and renamed (checkout_5_confirm_WAUE_HTML_WA_Universal_Email_1.php)
I ran the UE wizard and selected to use this file as template.

When I click this button on checkout, I get an error message.

It says:


( ! ) Notice: Undefined variable: madelena_cart in C:\wamp\www\madelena_prototype2\checkout_5_confirm_WAUE_HTML_WA_Universal_Email_Bank.php on line 7

Do you know what I'm doing wrong?
Is there a better approach? Or an easy fix?

Thanks,
