Since version 1.0.0 of Streamer.bot the if/else sub-action has changed to be more flexible and also allow you to run singular sub-actions in a True or False Result Group.
Pre-1.0.0 this field was called "Variable" as you'd directly write the variable name itself in it, like userName.
Now it's a general input field, so to check the value of userName we would write %userName% as using %% will give us the value of the action variable.
You can now also use Inline Functions and globalVar to check the value of a global persisted variable directly.
This is the same as in pre-1.0.0, so basically the operation of how you want to check the value of the Input field, and the value of the Value field.
