So others that are interested will know...
When I patched the code per the suggestion in the referenced link, I wanted to keep available the original code, in case I made a mistake typing. So I added a couple slashes "//" to the beginning of the original code thinking this would turn it into a comment.
This apparently caused the JavaScript error I was getting. Ray deleted the line of code and everything is working fine.
Thanks to the tech supt. folks.
