Create Variable - Greyed Out

Hi, got a quick question that I do not understand why this is happening on the UiPath interface.

Continuing my understanding of creating new variables, there is an alternative option described in one of the UiPath Foundation 1 - video tutorials to create them in a faster way by typing in the result output in an “input dialogue”, but for some reason, this option is greyed out from my UiPath view… why is that?

This is related to the “Set Name: variable name” command.
