Love the module. Absolutely brilliant.

Issue I'm having is that on the checkout page where it states "Total excluding GST".
It actually states the total "inclusive of GST".

This is what it looks like:

Subtotal: $119.00
Standard Delivery (Included): $0.00
Total excluding GST: $119.00
GST: $11.90
Order total: $119.00

Any help or thoughts as to why it's including GST on this line rather than excluding it?
Many thanks and thanks again for this module!
