Understanding taxes

Hi,

just installed opencart on my localhost for testing purposes .. works fine so far but i do have a problem to understand how taxes are working in this script.

I've created a tax group and according to this a tax (e.g. 20%).
I've created a product and choosed the tax for this.

Anything works fine but:

I need to display the taxes (total) like

Subtotal:  151.12€
Flat Shipping Rate: 148.17€
Total: 299.28€
Taxes included: 12.34€


in the following "modules":

- checkout_confirm
- account_invoice
- crontroller=order&action=update (admin)

as also in the mails to customer/admin

Any tricks for me how to include this?

Thanks!

Any hints for me pls?

I have posted a howto document in the contributions area.

The download is a zip file containing an MS Word document which you just have to rename to have a .zip extension.
