Summing cells based on mulitiple criteria over mulitple columns

[troy00]

[font=Verdana, Arial, Helvetica]Okay...I have looked and looked and have tried several approaches, but
nothing seems to be working. I call for your help.

I have two tabs - first tab contains the data, second tab contains the
formula.

Data tab:
Column A = contains value for Criteria 1 [N1/N2/N3/etc]
Row 1 = contains value for Criteria 2 [x1/x2/x3/etc]
Row 3 = contains value for Criteria 3 ["z"]
Row 2 = contains value for Criteria 4 ["y"]
DATA RANGE = Columns/Rows B5 through Z100

A B C D E
1 x1 x2 x1 x2 x3 (variable value, but some equal to others)
2 y y y y y (constant variable)
3 z1 z2 z1 z3 z4 (variable value, but some equal to others)
4
5 N1 # # # #
6 N2 # # # #


Formula Tab:
Column A = Name Value which is also the criteria for Criteria 4

A B C D E
1 x1 x2 x3 x4 x5 (criteria = to Data tab row 1)
2 z z z z z (criteria = to Data tab row 3)
3
4
.
.
10 N1 =FORMULA
11 N2

Formula Entered on Formula Tab in cell B10:
=SUMIFS('DATA'!B5:Z100,'DATA'!A:A,'FORMULA'!A10,'DATA'!1:1,'FORMULA'!B1,'DATA'!3:3,'FORMULA'!B2,'DATA'!2:2,"y")

I believe the error is to with the sum range as it spans over multiple rows & columns.

Can anyone help me out with this? Thanks in advance. [/font]
