I have a spread sheet that looks like this

CO. Month Amt
Apple 11 $5000
Apple 12 3000
Orange 11 500
Orange 11 300
Apple 11 50
Peach 11 6000
Apple 11 150

In a differnet spreadsheet, I want to look up each company based on the
month it is found in and sum the amounts given.

Example
November Spreadsheet
Co. Total
Apple 5200
Orange 800
Peach 6000

December Spreadsheet
Co. Total
Apple 3000
Orange -
Peach -

This will continue throughout the 12 months. the first spreadsheet is the
main one where information will be inputed. I need the formula to not only
look at the month but who the company is as well. I used to SUMIF function
when i was looking at just the month in general but now I need to add to the
formula so it will only add those rows that have the correct company
attached. Help will be much appreciated.

Thanks,
Sally
