Filter range

[vvvvvvvvvv]

I want user can decided the range of the dimension. Initially, I want to create a range slider but no extension is work for this purpose. So I start to use drop down in variable input. But when I set the formula into Dynamic value of the drop down : concat(valueloop (1,20),'|')

QS recognizes the field as string not number.

How to deal with this?

Valueloop alone gives the range why using concat here?

 But I need to put it into the variable input...
