Tested it in IE 7 on my test for, (Server 3) didn't work for me either. Trying to make it work though.
But try this one, idk if it will work or not.
<script>
var CopyRight = "Testing, testing. 1, 2, 3.";
//Created by Agent Moose (smcodes.smfforfree3.com)
$("#footerarea").innerHTML += "<center><span class='smalltext'>" + CopyRight + "</span></center>";
</script>
