formula syntax

[#1]

Helo,

I've got 2 values.

Value 1 = Sum (Aantal)
Value 2 = (Sum (Aantal1))/ Max (Maand1)

Value 1 returns 150
Value 2 returns 250

Now I want Value 1 - Value 2 = -100

I've tried (Sum (Aantal)) - (Sum (Aantal1))/ Maand1) but does not work

Sum

(Aantal) - Sum (Aantal1)/ Maand1 also does not work

You missed max

Sum (Aantal) - Sum (Aantal1)/ max(Maand1)
