Usgin "% of" with a Custom field

Posted by Thomas on October 26, 2001 8:48 AM


I'm trying to do this. I have 5 columns (Argentina, Chile, Uruguay, Mexico, USA) that i use in a pivot table, and i get a table showing

Product1 Sum of Argentina 18
Sum of Chile 5
Sum of Uruguay 14
Sum of Mexico 9
Sum of USA 17
Product3 Sum of Argentina 10
Sum of Chile 8
Sum of Uruguay 14
Sum of Mexico 9
Sum of USA 3
Product3 Sum of Argentina 19
Sum of Chile 10
Sum of Uruguay 13
Sum of Mexico 12
Sum of USA 8

I Created a custom field to get "Total" = Argentina + Chile + Uruguay + Mexico + USA

What i want to do is get the % of each country over the total for each product. For example, product1, Argentina should be 18/63.

The problem is that when i try to use the "% of", the field doesn't show my custom field.... can i do something ?

Your data isn't organized properly to get the full
benefit of a PivotTable. Your data should be in
First Normal Form (1NF) which means you can't
have a repeating group. Your 5 columns of
countries is a repeating group. Instead, you
should have a single column labelled 'Country'
and your country values (Argentina, Chile,
Uruguay, Mexico, USA) should be on separate
rows. Once you've reorganized your data getting
'% of Total' can be easily accomplished.

Problem is that there are several more columns, something like Argentina - People, Uruguay - People, in which each column is the answer to a specific question, so that doesn't allow me to change the organization of the data.

Well, then you also have a 'People' repeating group
which needs to be "normalized" as well. So it'd
look like this...

... etc.

You may want to review "Guidelines for creating a
list on a worksheet" in the Excel Help.

here are the current state populations as a
