@jwk,
Can you please check browser console for error Uncaught SyntaxError: Unexpected token ) - csvtest-update.htm:72. It seems like there is some mismatch of brackets in your code.
If you are facing any other issue, kindly create jsfiddle or share static html/php files over onedrive/google-drive so that we can understand your code better and help you out?
