What portion of the script should I change?
Currently it reads like this in Appearance > Editor > footer.php
<?php if(is_home()) {
$twitterID = get_option('T_twitter_ID');
$twitterURL = "https://twitter.com/statuses/user_timeline/".$twitterID.".json?callback=twitterCallback2&count=1";
?>
<script type="text/javascript" src="https://twitter.com/javascripts/blogger.js"></script>
<script type="text/javascript" src="<?php echo $twitterURL; ?>"></script>
<?php } ?>
