Answer 1

I don't know if you changed things or not, but happy isn't added to the list as line 8 generates a runtine error. 'getElementsByTagName' returns a list as indicated by the 's' of 'Elements'. Trying to use the list as a single element fails.

Change 'total.appendChild' to 'total[0].appendChild' to reference the one and only 'ul' tag and happy will be added to the list. However, you HTML will look like this:
<ul>
<li>rat</li>
<li>goat</li>
<li>woman</li>
<li><text>happy</text></li>
</ul>

As @John wells said, replace total with total[0] and your statement will look like this:

total[0].appendChild(add);
