Can variables used in functions?

Hi there,

i have a big Problem.

Imagine, I want to calculate the total Price of different parts, that have a Price payed, a amount bought and an amount used.

For example:

ingredient1 Price: 5.00 Euro
bought: 100ml
used: 20ml

Price / bought * used is the solution for calculating the Price of the amount used. Thats easy.

But what I one or more ingredients are not bought (so bought is “0”) => results in Division through Zero.

Is it possible do something like this:

If incredient1bought = 0 then totalPrice = totalPrice
Else totalPrice = totalPrice + ingredient1price / ingredient1bought * ingredient1used

If incredient2bought = 0 then totalPrice = totalPrice
Else totalPrice = totalPrice + ingredient2price / ingredient2bought * ingredien2used

If incredient3bought = 0 then totalPrice = totalPrice
Else totalPrice = totalPrice + ingredient3price / ingredient3bought * ingredien3used

So totalPrice is updated whenever an “bought” value is not “0”

Can totalPrice be used as a variable the Price of each used ingredient is added like this?

I can think of a Workaround creating a Price field for every single ingredient, but this could be a heavy Workaround 🙂
