filter by using Variable Input extension (input box)

[ganadara]

I want to select values in fields(not variable) by using Variable Input Extension.

For example,,

1.

'Age'field has some values, (20, 21, 22, 23, ..., 29, 30)

'vAge' variable is used in Variable Input Extension as Input box

2.

When I enter '<24' into Input box of vAge's Variable Input Extension, I want to select 20, 21, 22, 23 in 'Age' field.

I know that it is possible by using input box of filter, but Is it possible in input box of variable input extension?

Actually, I want to make  'where clause' of on-demand service, not  using 'in ( , , )'

How can i do in qlik sense.

Thank you
