Your parameter names should follow naming rules. From MDN

A JavaScript identifier must start with a letter, underscore (_), or dollar sign ($); subsequent characters can also be digits (0-9). Because JavaScript is case sensitive, letters include the characters "A" through "Z" (uppercase) and the characters "a" through "z" (lowercase).

Youre basically almost there, so good job on that. Keep in mind parameters are there to call in different numbers. If you put 12,10 for them, then this function will always have those numbers in them. Thats why we put names for it so when we do CALL the function, we ADD the parameters afterward because sometimes you want different numbers inside. Check below to see an example:

function max(smaller, larger){ if (smaller < larger){ return larger; } };

alert(max(1,2));

This way we can call the function and put any number in it.
