once i create a pivot table, i'm trying to group items and it seems most of
the time i cannot, for items that are numbers (not general). i have a "age"
column it works with, this is a "general" field, not a number field and it
works fine. i have other columns, such as height and weight, and these do not
work (these are in cm and i've tried both general and numbers). any advice
on when the grouping works and when it doesn't would be great.
