Basic JavaScript - Compound Assignment With Augmented Addition

Hello Friends,
I am stuck here …what is the wrong with this code?

Your code so far

let a = 3;
let b = 17;
let c = 12;
// Only change code below this line
let a = a + 15 ; 
let b = b + 26 ;
let c = c + 19 ;
a += 15;
b += 26;
c += 19;

Challenge: Basic JavaScript - Compound Assignment With Augmented Addition

Link to the challenge:

The first problem is you are re-declaring the variables. The other problem is that the test want you to convert/replace the equivalent of myVar = myVar + 5 with myVar += 5, but you are keeping the old code and adding that after.
