microsoft outlook 2007 Tasks, user defined Custom Fields?

[akasixcon]

I listed a couple of things called:
Apples, Cake and Hotdog
I wanted to make a custom field called "Type" but instaed I could only
edit
it using "Company" and added the following fields:
Fruit, Dessert and Meal

I could go "Field Chooser> New" and define my own however I cannot put
values in those fields.

Any idea how?
