54,668 PointsHave you run this through the console to check for errors? The first one is:
Uncaught SyntaxError: Unexpected token else on line 25
This is due to using a semicolon on line 23 where there should be a bracket
if (li.className === 'responded');
should be
if (li.className === 'responded') {
With that fixed the second error is:
Uncaught SyntaxError: Unexpected token else on line 29
Here you are missing the closing bracket for the if (isChecked) statement
else {
should be
} else {
I'll leave the rest for you
