Displayed price 0,-

[tromas]

If I set a special price (discount), which at that moment I could use, so I visit the Row listing displays everything correctly, but the product detail I see the price 0, - (for goods, which is set for combinations). It is clear to me that the error will be somewhere in product.tpl, but I can not figure it out where. Can someone please advise?

Possibly even - when I set off for a group (collectively), so I get a discount in Row listing in the basket it appears too well, but in detail goods are displayed price before discount (no old price crossed out, no text rebate ... )
