help with job post on craigslist

I am trying to place a job posting on [login to view URL] and the posting does not show, but it shows in my account page listings. I am looking for someone who could look at my ad and figure out why it is not posting, and post it successfully. I am a graduate student conducting research in that city and I am looking for participants to share their opinions about their news habits. The craiglist help forum has not been helpful at all to figure out why my job ad does not post.
