VAT question

In some European countries you have different VAT for different articles. There is a special rate for some wineries. So wine could have a VAT of 12%, cakes are 10% and some others are lets say 20%. How do I handle this?
Price is VAT included but at the Grand Total page it should say something like
Total is xxxx.xx
VAT 12% = xx.xx,
VAT 10% = xx.xx and so on.
I can't figure out the rule in the tax field, although I have a coulumn for it in the database

in the cart object, you would need to have a column for ProductType

in the add to cart button, set the ProductType to mark the tax rate it falls into.

for example, if its tax rate is 10% set ProductType to 1, 12% use 2, 20% use 3, etc...

then on the tx tab of the eCart object, create a tax rule for each rate using the "Based on items with aa specific column value" calculation:
10%:
Total of 'TotalPrice' where 'ProductType' has a value of '1' 'times' '0.10'

12%:
Total of 'TotalPrice' where 'ProductType' has a value of '2' 'times' '0.12'

etc....


make sure the cart display is set to show the tax rules individually.
