Tell us what’s happening:

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!";

a=6;
b=15;
c = "I am String!";

I don’t understand why this is not working properly.


#3

Even when i put var next to a ,b i doesn’t work

The instructions indicate that you are not to change code below a certain line which you have. It is probably best to use the Reset All Code button to restore your workspace.

Here is an example to help you

var x; //this variable is declared but it is not initialized
var y = 5; // this variable is declared and initialized to 5

y = y + 2; // now y is 7

Here is a walk-through of the challenge
You have to initialize these three variables to some values

// Initialize these three variables
var a;  //change this line to initialize a
var b;  //change this line to initialize b
var c;  //change this line to initialize c

so that after the below code completes


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

value of a will be 6, value of b will 15 and value of c will be “I am a string”
