Uninitialized Variables - some feedback please

Tell us what’s happening:
Hi, i’m learning javascript on my own, as i’m also in a bootcamp. I’ve initialized these variables by assigning them values, yet still not able to move on to the next round. Please advise.

Your code so far

// Initialize these three variables
var a = 6;
var b = 15;
var c = "I am a" + "String!";

// Do not change code below this line

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

Link to the challenge:

The instructions for this challenge tell you exactly what values to use when you initialize the variables. Look at what those are.

I did that already, but running into issues with the understanding why “I am a String” still reads as undefined. Thanks.

It isn’t undefined. c must not be undefined AND it must contain “I am a String!”. It is failing on the second condition.

What three values do the instructions tell you to initialize the variables to?

solved it , by going through some of the older questions about this. I’m still trying to learn how to learn
