Duda tax

[PrestashopTrackglobe]

At the store I'm developing http://www.eluniversodelperro.com/tienda/ I'm in the process of checking all the modules, (payments), product IDs, etc., but the thing is that if I place a VAT product combinations (in "General") of 18%, and then add the Combination, for example:

Color: Red
Reference: 0000001
Wholesale Price: 5.42
Price: 9.45 (I like that these 9.45, 8 and was the base peak and the rest impnible VAT, ie that this included), the thing is that if I have to change something or I touched something that no was (the latter I think not) because I can not get to work (for example, when you visit a product with VAT you ppone: X € VAT included, but only puts in the combinations X €, help as this is very, very important and necessary for my store because I have more than 80% of combination products.

Thank you very much for your help and time.

A greeting.

PS: I could say that file. Tpl is referring to the image in the category in which these and subcategories when entering a? (I mean that when you enter combines section: "Dog", it shows the icon for that section (I would like the image of the category in which they do not appear, but if the subcategories for gnar space) and after sub-categories and products.
