No, in fact it never did!

That's an internal local function argument/variable.

So it is a a name/id of a html element you are referring there!

Therefore, you were accessing that element directly by id/name.

Lots of declarations instructions and values throughout the script 

are depending on that element. So, missing that element will cause

a general failure.

 

Therefore declaring: 

var calculator = document.getElementById('calculator');

(anywhere in your script)

May just bring it all back on gear. Cause there's no other 'true' error

there.
