Combination 2 discounts

[tromas]

Hello,

please help anybody if you can. I have 2 specials prices - one for mass group (in %) and one at specific goods. Everything is fine until the order counting discounts. For example - price is 10, group discount is 10%, one item has 1 discount. The final price should be 8,1,-

1) In a list of items it counting first the spcific discount, than in % (its corect). Example - there is 8,1,-
2) Product Details counts it conversely (its wrong). Example - there is 8,-
3) In the cart again counts as 1). Example - there is 8,1,-

Since the bulk discount in% - prices vary, of course. Counting discounts according to 1 and 3 is perfectly fine, I just needed to take it in detail and display the goods. Using Presta 1.6.0.14 version.
