WPEC Tax not showing

Hi!

My problem is that tax is not showing on purchase receipt. It is showing before you buy anything, but not on the receipt.
The problem is also described here and I’m from Denmark too – though I’m not using the WP e-commerce style Email. I just installed the Email Template Plugin though, but it made no difference to the content.
So what can I do to make tax showing on the receipt?
It is possibly to see for yourself here: Babykaos.dk and feel free to test-buy as my shop is in testmode.

Thank you very much!
