Answer 1

If I am right, the code should check the sum of the first row?
I make some changes in js file.

Fixed error:
- missing () in if statement

Removed:
- multiple functions with the same name

Added:
- NaN check for the <td> value
- convert <td> value from String to Number for calcuating row sum
