Date fields won't save

I'm not really sure what info you need to debug this or tell me what I'm doing wrong, but I'm attempting to filter nodes based on a CCK Date field (not datestamp, I altered the content type to use Date instead of Datestamp). I've tried a couple of different filtering options: Custom Date Range, Before, Within the last 3 months, and none of them seem to be affecting the view. I'm displaying the view as a block on only a single page, and the view is also providing a page. Any ideas?
