How to add a correct prices into blockbestsellers module

[2Nine]

Hello ladies & gentlemen,
I've tried recently to update my blockbestsellers module to show the prices of top selling products. I added just this string:

{displayWtPrice p="'$product.price'"}

which I worked outta some different module. And it works, but not correctly. The prices are weird, like they were not converted into the right currency. I've tried to modificate it in all possible and impossible ways but no good result. So if anyone knows, please tell me

for me it worked by adding this where i wanted the price for the first product to show:

{$best_sellers.0.price}

for second product:

{$best_sellers.1.price}

and so on....
