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

var a = 5;
var b = 10;
var c = "i am a" ;

// Do not change code below this line

a = a + 1;
b = b + 5;

The challenge is trying to teach you the difference between declaring variables and initializing variables. When the challenge first loaded, you had:

var a;
var b;
var c;

Those are variable declarations. There are no values assigned to them at this point.

You are supposed to initialize those variables. Initialization is when you assign a value to a variable at the same time it is declared.

You should not both declare a variable and then later initialize variable. Reset the code and try again.
