Extra column (expression with difference) in horizontal straight table

[bartvanwetten]

Dear all,

I have following challenge. In attached QlikView document you'll find a horizontal straight table. Now I want to have a third column per month wich shows me the difference between 'resultaat' and 'prognose'.

Can anyone help me out on this one?

Thank you all in advance.

Bart
