Taxes are calculated correctly but not shown

-- url of the page with the problem -- : kfz-schabacker.de/neu/index.php/de/compo...op/product/6-hgfhfgh
-- HikaShop version -- : 2.2.2
-- Joomla version -- : 2.5.16
-- PHP version -- : 5.3.3-7+squeeze17
-- Browser(s) name and version -- : Firefox

I have absolutley no idea what happend but suddenly it works without doing anything. This is very strange. Well..consider this Problem solved for now.

I looked throught this forum now for about a hour but there was no solution that worked so here i go:
I entered the Tax zone and tax rate correctly into hikashop and according to that the prices on the backend
are automaticly calculated right. - thats good But...the frontend only shows the prices without tax,
even i tell hikashop to show me both prices it shows me the price without tax and then the same price with the
notice its without tax. I have to say i have no Menu item connected to the producs listing. I only use a Module to show the producs on the mainpage. I already tryd to change the settings in the module as i thought they are somehow connected but it seems not.
I can give a english login if needed.

Hi,
The solution was to set the "Show taxed prices" option to Display both through "Hikashop->System->Configuration->Main"
