Variant Pricing Error

Hello All,

I have a scenario wherein I need to know the values of two characteristics to determine the price . For eg. IF the colour of the bike is RED and the engine is a 100 cc the price should be 45000.

In my case I have created 2 characteristics COLOR and ENGINE and assigned these characteristics to class ZDETAILS.The configuration profile has been maintained but the price is derived on just the value of RED. A combination of COLOR and ENGINE is not fetching any price,

Can some one please help me resolve this i.e. how to write the dependency on two or more characteristics values.
