Thank you very much for the reply. I think I explained not clear enough, what it does.
In my case: If I check the option, it adds the price to the additional services correctly and it counts that position correctly. But when I add for example quantity of 2 or 3 for the main product, it automatically doubles or triples the position for the option too.
If it would leave the price for the options without changin with the quantity of the main price, it would be all fine.
Thank you
