Problem with NSSearchField in Apple's Core Data Tutorial

I am trying to follow Apple's Core Data tutorial <http://moourl.com/x5xbg
> and I am stuck on getting the NSSearchField to actually work. 
Another list member was helping me off-list and sent me a working nib 
file. When I dropped it into my project, however, it did not work; the 
search field accepts input but the filter is apparently not applied to 
my NSTableView.

At this point, I'm not sure where I might be going wrong, so I 
uploaded my project to the web. If anyone can take a look and help me 
decipher where I'm off track I'd greatly appreciate it. <http://jamiephelps.com/CheckIn.zip
