Hi,
http://redballoontoystore.com/w/ is a self-hosted WordPress.org blog, which we really can't help with.
To clear up any confusion, WordPress.com and WordPress.org are two different entities.
WordPress.org has complete support and documentation sites for self-hosted/installed versions of WordPress via their Codex and Support Forums.
You can try the following for the label:
[sourcecode language="html"]
AT&T
[/sourcecode]
If that doesn't work, please contact the WordPress.org Support Forums.
