I've actually found the cause of my problem.
Quite foolish of me. I had earlier experimented with having all my
javascript after the footer of the page rather than in the <head>. So I had
2 instances of the script tag that contained this code on 1 page.
I am grateful to everyone for their help. I learned much and was able to
decrease the number of lines of code needed.
