C10, plus a number of other cells, holds
the relevant data on each worksheet

Specifically Define: "plus a number of other cells".

Are the cells in question in a contiguous range?

I have a collection of worksheets, each with the same format of report, and
a
summary sheet which shows the name of each worksheet.

I want to create a selection sheet, where I can mark each of the required
sheets and have the selection sheet show the summed data.

I have tried :
=sumproduct(SheetA:SheetZ!C10,SheetA:SheetZ!$A$1), but it returns a #REF
error
(A1 in each sheet holds a 1 if the sheet is required to be included.)
(C10, plus a number of other cells, holds the relevant data on each
worksheet)

Any help would be appreciated
