Summing up child / detail cells to Parent / Summary

[DNA007]

Good morning all, i have scoured through MR Excel, and many others but have not had any luck. This maybe due to not using the right keywords in google. Alas, i have had to create this post for help.

The best way to describe this issue is something that is done automatically within MS Project. I need a formula that can Sum the detailed task (hrs) to the Summary Level above, and that summary to the level above it yet again.

[TABLE="width: 562"]

So, as can be seen in the table above (wasn't sure how to attached the actual excel sheet in), the detailed task will be the lowest level of any summary task. These need to be calculated to the level above, which will then need to cascade up to summary lvl 0 (overall project duration).

OFFSET is not working as the task/ summary level can appear anywhere on the excel sheet and is not confined to set rows.

Any help would be greatly appreciated. Thanks

Any luck? for something that is so basic in MS Project its annoying how difficult its turning out to be mimic in Excel.

Morning all, this might make it easier to understand, I am after a formula that will be able to calculate per the Hierarchical level....

So in the example above (original post)....

Level 1.3.2.2: would roll up to level 1.3.2, which in turn would go to level 1.3, and ultimately into 1.

I realise this might not be as easy as it sounds, so any ideas would be greatly appreciated.

Thanks
