Why do these divs remain visible?

Head out to http://brucegust.com/portfolio/verizon/index_static.php#. Click on the (6) to the right of the July month listed along the right hand side. You'll see a list of states appear that look like this:


The idea is that when you click on one of those states, all of the states' entries within the calendar remain visible while the other states are hidden. It works! Except for the "fried wire" and "big waves" entries. Both of these are "Florida" ids. When I look at my Javascript code, it appears sound and the Florida entry on the fourth (another Florida disaster) goes back and forth between hidden and visible just as it should. But I'm missing something with the Florida entries on the 7th and the 9th. Why will they not hide on command?

What do you think?

It's because you have multiple divs with id="Florida". You can't have multiple elements on a page with the same id. Instead, you can use class="Florida" and select all your elements that way. If you're using jQuery it might look like this:

$(".Florida").each(function ()

An element's id attribute must be unique.  So only one of them on the entire page may have id="Florida".  the same goes for the others.  By contrast, elements may "share" the same "class" values.  So, in your case, look for all your:
<div id="Florida">...</div>
and change them to:
<div class="Florida">...</div>

Then in your js you need:
function Florida()
  $(".Tennessee, .Louisiana, .Mississippi").hide();
return false;//don't forget this.
function Louisiana()
  $(".Tennessee, .Florida, .Mississippi").hide();
return false;
function Mississippi()
  $(".Tennessee, .Florida, .Louisiana").hide();
return false;
function Tennessee()
  $(".Florida, .Louisiana, .Mississippi").hide();
return false;
