Actually, it *doesn't* work fine in Mathematica.  Here's a very important 
criterion to understand for working in Player.  If the file does not work in a 
fresh session of Mathematica without requiring Shift+Enter or initialization
cell evaluations, then it will definitely not work in Player.

For a Manipulate, one typically uses FullDefinitions as an easy way to slurp the 
code into the dynamic evaluation.  Another way is to use the Initialization
option.

Your .nb file does not pass this test in a regular Mathematica, so you cannot 
expect it to work in Player.

For what it's worth, learning to fulfill this criterion will not only fix Player 
documents, it will generally make your Mathematica interfaces more robust and 
easier to use, since their functionality won't rely on a history of potentially 
obscure user actions.  I mentioned some other issues for making solid interfaces 
in my talk at the 2007 Wolfram Technology Conference.  My talk notebook is 
here...
