What's wrong here?

Whats wrong here people?

Your code so far

// Initialize these three variables
var a;
var b;
var c;

// Do not change code below this line

a = a + 1;
b = b + 5;
c = c + " String!";

var a = 6;
var b = 15; 
c = "I am a" + c;

You are only supposed to change the code above the following line:

// Do not change code below this line

In addition, and for future reference, you cannot declare a variable with the same identifier more than once—you have both a and b declared with the var keyword twice.

I think you are trying to make things match the output of the tests, but that’s actually already what the code below the line // Do not change code below this line is already doing. Reading through the instructions again may help:

Initialize the three variables a, b, and c with 5, 10, and “I am a” respectively so that they will not be undefined.
