Answer 1

You're close. Really, really close.

The only problem is that you're not actually invoking either of the functions. This is all you're missing: ¹

lol();
rofl();

_{¹ Well, that and some semicolons.}

Answer 2

You dont have to do anything other than call the functions. You have set them up properly, but if you dont call them then nothing will happen.

x = 10
lol();
rofl();

function lol(){
    x = 5
}
function rofl(){
    alert(x)
}
