Your Get[] operation reads in the Mathematica expression corresponding
to the notebook document itself. It does not evaluate the cells therein.
You can use the autogenerate package feature of the front end to save
out Input style cells in a companion package file (e.g. mynotebook.m)
that contains evaluatable forms.
I have posted some articles in this newsgroup in the past describing
step-by-step how to do this. You can retrieve one of the archived
postings at Deja.com.

Note that the name of the notebook option InitializationCellLoading
has been changed to InitializationCellEvaluation for Mathematica 4.
Documentation for this option can be found in the online help by
evaluating this expression in a notebook.
