MPG rating showing 0.0 and "-" for two months

First, I love this site. I've been using a spreadsheet for the last two years so I'm anxious for the new data I can pull in with this site.

I'm trying to figure out why my MPG rating has been 0.0 for the last couple of months. I imported a lot of data and that seemed to go ok, but now, when I look, even the data that I manually enter is showing blank. I've tried looking through the data for inconsistency, but can't find any. Any advice?

Code:

10/01/09          69.0          13.575          $2.46          -          Chevron          

10/01/09         535.0         2.033         $2.46         -         Chevron         

9/17/09         38.0         13.027         $2.46         -                   

9/16/09         34.0         1.939         $2.58         -                   

9/15/09         282.0         1.682         $2.38         -                   

9/13/09         384.0         8.407         $2.38         -                   

9/03/09         42.0         14.374         $2.62         -                   

9/02/09         357.0         1.540         $2.60         -                   

8/26/09         352.0         13.695         $2.60         25.7

Many of your fuel-ups are marked partial. When you enter a partial fuel-up, Fuelly doesn't calculate an individual MPG for that fuel-up, and the one immediately following. Fuelly needs a new full-tank baseline to start calculating MPG for individual fuel-ups. However, the fuel-ups do contribute to your average fuel economy. Here's a bit more info: How do I account for partial fuel-ups? and Why do I have to fill the tank all the way up every time I buy fuel?
