Tell us what’s happening:
Describe your issue in detail here.

  **Your code so far**


// Setup
var sum = 0;

function addThree() {
sum = sum + 3;
}

// Only change code below this line
function addFive(sum) {
sum += 5;
}
// Only change code above this line

addThree();
addFive();

Challenge: Understanding Undefined Value returned from a Function

Link to the challenge:

2

Create a function addFive without any arguments.

You missed this instruction. You are modifying your input rather than the global variable.

3

so then how could i correct the mistake?
ps: thank you for the input

4

The instructions say to create addFive without any arguments, so I’d remove the argument you have for your addFive function.

5

if I do that that makes the last task incomplete? I’m a bit confused.

//                ↓ THIS ARGUMENT SHOULDN"T BE HERE
function addFive(sum) {
//                ↑ THIS ARGUMENT SHOULDN"T BE HERE

oooh I see that makes a lot of sense. So the solution was to just not put an argument there and have the equation below as sum += 5
thanks a lot

Yep. I’m not wild about this challenge because generally you should never modify global variables without good reason but :man_shrugging:
