Is the "upper" parameter something the instructor made up?

The explanation isn't really sinking in for me.

How is the value of "upper" being defined? Is it pre established by MDN similar to "toUpperCase"?

Hi Quierra - If you are referring to this part of the code: function getRandomNumber( upper){

then "upper" could be anything, you could name it "higher" or "bob", as long as you refer to it with the same name within the function itself. It is similar to stating a variable that will be used in the context of the function, and is being set outside of the function when the function is called.
