Change Invoice Wording from "Group Discount" to "Customer Discount"

[OLD MAN]

I had it but I have been reviewing over 2 hours to find it again and I gave up and now I am asking for some direction. I want the Group Discount on the Invoice to read "Customer Discount".

Sub-Total: $255.36
USPS First Class Mail (USPS First Class Mail): $5.00
Group Discount: -$63.84
Total: $196.52

When you want to change text and need to find it or find code etc. ... go to the Tools ... Developers Tool Kit ... and in the bottom input box enter what you are looking for such as:
Group Discount

and select your Catalog or Admin or both and click Search ...

This will help you find where the define statement(s) is/are located ...

Then, depending on whether or not there are templates and overrides, you can make the changes you need ...

Something like a language module file would have templates and overrides for it such as:
/includes/languages/english/modules/order_total/ot_group_pricing.php

can be customized by copying that file to:
/includes/languages/english/modules/order_total/your_template_dir/ot_group_pricing.php

and changing the text ...
