I have a column with age values called "AGE". I listed them in a straight table. I then created input variables where I can enter the minimal (ageDown) and maximum (ageUp) age
Sum({<AGE={">=$(ageDown)<=$(ageUp)"}>} AGE)
The straight table now shows all values which have an age between the parameters I entered. Works fine, only one problem: I also see 0 values.
