Help with Creating a Subnav Bar

I am attempting to edit the subnavigation menu of the navbar. I seem to have broken my main nav links as well as the sub nav links and am not sure why and how to fix it.
My “Home” tab is supposed to scroll to the sections under the “Home” page. The “Volleyball” tab is supposed to scrolls to the sections under the “Volleyball” tab, so on and so forth. I had the “Home” tab working correctly, but when trying to create the same effect for the “Volleyball” tab, it seemed to break all of them.

Here is the preview of the website I am working on:

Can anyone help me out? Thanks@
