Expression inside expression how to do?

[Roket]

Hi
I have a value from the Webhook node and a Value from the IF node (Current node), in the Set node I want to do something like an expression inside an expression, how can this be implemented?

You simply have to lose the "{{}}"

So for example like this:

{{ $json[ $json["whatever"] ] }}
