I have chosen the basic settings in vm admin the way that Tax is included when showing Prices. The Story shows Prices with included Tax, and, the Tax is shown as extra value below, because this is a duty in Germany.
But that did not affect the Scroller. That's the reason I guess that maybe another parameter has to be called.
I only want it to show the Price with included Tax. In Germany you normally show the Prices like this. The Scroller shows it without included. Well, i will try to find the Parameter in the Module Code. I guess that it is possible to change it.
