Do you have a question?

If so, please edit your post to include it in the Tell us what’s happening section.

Learning to describe problems is an important part of learning how to code.

Please tell me what is the error in the code, how to make the variable with not undefined.

[JeremyLT]

Nothing is undefined.

@Saharamalo

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

The challenge wants you to set these values here so that when this part runs

@Saharamalo

// Only change code above this line
a = a + 1;
b = b + 5;
c = c + " String!";

then a will hold the value 6, b will hold the value 15 and c will hold the value "I am a String!".

They tell you what values to use:

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