Complex calculation

Hello

I’m trying to calculate a price based on a few answers.

The form logics branches to 2 cases, and each case has 3 cases.

I’ll try to describe the calcuation:

Let factor1, factor2 = constant1, constant2

Let price1, price2, price3 = constant_price1,  constant_price2, constant_price3

I will then need to create a new factor number, and multiply it by one of the prices.

So if the user answers question 1 with A, I’ll use the answer multiplied by factor1,

and if they answer B, I’ll use the answer multiplied by factor2

I then need to use the results and multiply it by either price1, price2 or price3, depending on the answer of question #2.

I’m unable to do it though, because I can’t save the new factor into a new variable.

What’s the solution for that?

Thank you
