Hi there and welcome to our community!

This is the starting code for this step:

// Only change code below this line
var a;
var b;
var c;
// Only change code above this line

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

You appear to have edited the bottom three lines of code, which shouldn’t be modified at all.
I would hit the Reset this lesson button and then only modify the three lines of code specified.
