I am working with multiple worksheets. I've split up the worksheets by
person (8 in total). I need to carry the calculations from each worksheet
into one that will total each person time by months.

Colomn A = Project No
Column B = Project Name
Colomn C - Project Manager
Column D - Expected Project Start Period
Column E = Expected Project Finish
Column F-W contains months (example: April '09, etc)
