Tell us what’s happening:
I can’t figure out what to do here, the questions are:
You should not change code above the specified comment.
Waiting :b should have a value of 7.
Waiting :a should be assigned to b with =.

:my code so far:

// Setup

var a;
a = 7;
var b;

// Only change code below this line

Please post a link to the step.

Do you understand how the equal sign works?
The left side gets the value on the right.

Eg let x=10;

Means that x will have the value of 10.
