Challenge 115 in Javascript

Tell us what’s happening:
I don’t understand what it’s asking of me if this isn’t correct? I’ve tried this so far:

var a = 7;
var b = 7;
var b = var a;

as well as,

var a = 7;
var b = var a;

Nothing. Thank you for your help!

Your code so far

// Setup
var a;
var b = 2;

// Only change code below this line

var a = 7;
var b = var a;

Link to the challenge:

It should be

var a = 7;
var b = a;

You declared a twice. and I think you cannot pass values like that.
