Perhaps you are using something like this:

document.getElementById("myDiv")

With HTML like this:

<div id="myDiv">Hello World</div>
<div id="myDiv">Hello Again</div>

In which case, you can't use the same ID for two div tags and the divs after your first one won't be affected by your JavaScript.

You can use:

document.getElementsByTagName("div")

To get a collection of all your divs, you could then test them to see if you want to do something with them, for example by giving them all the same class.
