why is getElementById("blah") null?

[mwbarry]

Why do I keep getting the error 'document.getElementById("content") is null'html

<div id="content">old text</div>

js

document.getElementById("content").innerHTML = "new text";

You need to show all of your code together. By itself, this is fine.

NB: the element you are targeting, should be on top , why the js should be at the bottom !

in other words. If you are going to have javascript execute on the page, and you are certain that the element exists, it's probably because your JS is running before the DOM has finished loading. If you are using jquery you can use $(document).ready(function(){}) or else use window.onload and make sure all your code is executing within na function assigned to window.onload instead. Let us know if none of that makes sense, lol.
