I tried to search other question like me but I don't find, I am sorry to disturb you for this stupid question
I am using V.M 2.0.6 with Joomla 2.5.4
probably the mistake is very stupid
I setted the tax in the section like picture
(http://www.essereobenessere.it/images/step1.jpg)
the calculation in product detail is ok 13 euro (this is the final price that i put in the section of setting article and I flagged the option automatic calculation of base price)
(http://www.essereobenessere.it/images/step2.jpg)
but when I go to final cart the page show me that the calculation of tax has been calculated on Euro 13 instead to show me final price Euro 13
