You have wrong syntax in HTML. Take a look near line 120, there you find <!--</div>--> leaving an element div without being locked inside a td.
Then you have a </div> the closest to line 198, and the same on the other table, between the last tr and </tbody>. This is invalid syntax.

This is very strange, I assume there are html with syntax problems. Can you show how to play this? You can create an example or show where you have that code?
