what am i doing wrong here?
They say JS global variables should be declared outside of the functions but I have been trying without success. I would like to declare several variables to be used on different functions. how am I getting this wrong? https://code.sololearn.com/W8YPA4z49efz/?ref=app

Before you trigger event in HTML page you need to first declare variable demo as
demo = document.getElementById('demo');
in the same HTML page's event attribute.
