Your FormClass expects all 3 fields to be optional (*required=False*). But your code in view always expects them to have integer values. And you end up multiplying values from two blank fields! Either you provide some default value to the fields or rewrite view to use *form.cleaned_data.get*with a default value as 2nd argument to it.
