Hi Chris:
The other commenters are spot on but they all failed to mention the URL builder tool which makes it much easier to build your urls. http://www.google.com/support/analytics/bin/answer.py?answer=55578. Sounds to me like you have coded the fields in incorrectly.
My most recent blog post explains the role of the Google URL builder tool and how it applies to tracking social media, specifically Facebook. The information on this page applies to any url you wish to track as a campaign - including short URLs! http://www.halogendesigns.com/blog/social-networking-in-business/tracking-social-roi-facebook-twitter-google-analytic/
EDIT: Wanted to note part of Curtis Noble's comment: "I would just leave the others blank. GA will pick up the keyword already from the search engine without you having to tell it what keyword you bid on."
