Summary sheet: Sum 'moving' cells.

[Shoop]

The individual worksheets represent different work scopes on a given project with each scope having different types and/or amounts of materials.
What I would like to do, rather than have several blank rows just incase, is have the formula on the summary sheet grab the subtotal from each sheet regardless of how many rows were added to the individual worksheets.

Here is the formula I currently use on the "Summary" worksheet: =SUM(Start:End!I12)

The image below is of a "Material" section on one worksheet. If materials are added, beyond (3) rows, the subtotal moves down and is then not part of the summary total.

Hopefully this is one of those easy fix on a Friday type question.

Thank you,

Why not insert a row above your table, then you can put the subtotal in that.

That will works, thank you!
However, can what I described be done? You know how those co-workers are, they like subtotals at the bottom.

Again thank you!

I don't know of any way to have a 3D sum which looks at different cells.
