Forgive me if this is something simple, I am trying to access a cost report for the project I have created and assigned resources to, I have set it up as follows,

PROJECT NAME
PHASE 1
task 1
task 2
PHASE 2
task 1
task 2
PHASE 3
task1
task2

The problem is I can only see the cost for the entire project not each phase which is what I would like, they are currently set up as the tasks are subtaks to the phases and everything is a sub task to the PROJECT NAME.

thanks in advance
