Variables calculation

Hi Qlik

I am trying to create a calculation with variables that looks like this:

TN/(fn+TN)

Each one of the parameters is variable that I created in variable expression (not script). Here are the calculations:

TN --> count({$<result={"tn"}>}[test ID])

fn --> count({$<result={"fn"}>}[test ID])

This calculation I trying to show in Text & Image chart like KPI (only measure). What I get is a blank window in the Text & Image chart.

What can be the problem with using the variables?

Thank you.

You need a dollar expansion for the variable to evaluate, give this and the related threads  a read to know better
