Tell us what’s happening:

Your code so far

// Setup
var a;

// Only change code below this lineWe
var a = 7;

Link to the challenge:

OK, There are really just two things you need to do.

  1. Assign the value 7 to variable a. You did that above, but there is no reason to include the var in front of it, because variable a was already declared at the top with var a;

  2. Assign the contents of a to variable b. In the example (shown below), they assigned the contents of myVar to variable myNum. See if you can use this example to know how to finish this instruction.

Hint: since b has already been declared you statement will look like:

b = ???;

You just need to fill in the ???
