Discount not given over price incl VAT

-- url of the page with the problem -- : www.vertoog.nl
-- HikaShop version -- : 2.3.2
-- Joomla version -- : 3.3.0
-- PHP version -- : 5.3
-- Browser(s) name and version -- : all
-- Error-message(debug-mod must be tuned on) -- : -

See the attached screenprint.
The discount of 15% not given over price incl VAT.

The right calculation would be:

Order 137,50
Discount 15% 20,63
Total 116,88

VAT 6% 6,62

We changed the VAT in the discount, but without any effect.

Hello Jan,
You should probably change the value of the "Apply discounts" option through "Hikashop->System->Configuration->Main"

That's it!

Thanks a lot!
