Use a variable to set which field a filter pane uses.

[JacobJones]

I want to use Qlik Variable Input to set a variable that decides what a field a filter pane is using. 

So the expression I am using in the filter pane is:

=if(vFocus = 'Case Processing Location', [Case Processing Location],
if (vFocus = 'Responsible Provider', [Responsible Provider]))

But this is not working.  Can anyone help me with the syntax or approach needed to make this work? Can a what field an object is using be changed this way?

Hey Jacob,

Have you solved your issue ?

What I used in my late projecst was this syntax :

=[$(vFocus)]

or even better, as the previous syntax may introduce brackets in the filter tab :

=[$(='$(vFocus)')]

It work like a charm on tables, charts but I don't know why, in filter pane the field does not change when variable value is changed ...

Anyone have encountered this issue ?
