[ic] SalexTax error with discount products

[Salvador Caballe]

Hello 

I need some help to use [discount] tag in a multi SalestTax (European VAT)
configuration.

If I try to use [discount] tag but  the tax calculation is always from 
regular  price instead discount price.

Is very easy to reproduce the problem in a default foundation catalog.

you  only need to do  3  changes.

1-
catalog.cfg

#SalesTax        __TAXFIELD__
SalesTax        multi

2-
edit tax field in a test country (Spain)

Table country.txt
Spain -> tax field :    default = 16%, books = 4%

3-
checkout.html

add this line  (25% discount in all items)
at top

[discount ALL_ITEMS] $s * .75 [/discount]

restart interchange

To check the error:

put any item in cart,checkout  and select country Spain.

The sales tax (16%) is wrong.
is calculated using regular price instead discount price.



best regards
Salvador
