Functions with two parameters missing instructions


In this section, it says to make a function with two parameters and I know how to do that, but what I don't know is how to pass 2 values to the parameters.

// Write your function starting on line 3
function perimeterBox(length,width){
    var perimeter=length+length+width+width;


You're doing it.


Whoa I am confused here so, is
Parameters and Arguments
is after
Functions with two parameters
right? Because today when I clicked continue on this skill, after finishing with the one before Parameters and Arguments (I forgot the name)it took me to Parameters and Arguments. So basically I didn't see this lesson any more. Maybe I have a terrible memory and I forgot I even finished this part already.
