Using a variable fieldname in a Filter List block

[StephenDunn]

Hi,

in a Qlik Cloud automation, within a filter block, I need to use a variable as the fieldname.

How would this look in the If statement?

Without a variable, the name is stated like:   'Required Fieldname'

I've tried replacing that with various options (after toggling the parsing option to allow JSON input) :-

  '{ $.requiredFieldName }'

  { $.requiredFieldName }

  =''{ $.requiredFieldName }'

  '={ $.requiredFieldName }'

and similar, but nothing I've tried is working.

Thank you.
