How to calculate product price dynamically using arithmetic operations on Attribute Values in Produc

Hi,

We have requirement like handset product price has to be calculated based on the contract period attribute and plan price(plan is another product which is part of another bundle product. It is being brought to configurator using linked Items).

Rerquirement is if contract period is zero --handset product price will not be applied any discount

if contract period is non zero and (plan price * contract period) is less than 40%(Handset product price) then handset product price will get discount of 40%

if contract period is non zero and (plan price * contract period) is greater than 40%(Handst Product Price) then handset product price will get discount of 100%
