Hi

Look at this:

Option Explicit
Option Base 1

Sub SumArray()
Dim TopCol As Long 'Rightmost Column #
Dim Col As String ' Rightmost Column Letter
Dim HeadersRng As Range 'Headers Row
Dim SourceArray() As Variant ' Array to receive Data Source Range
Dim SumArray As Variant ' Array summarizing SourceArray
Dim BotRow As Long
Dim i As Long
Dim j As Long
Dim k As Long
Dim r As Long
Dim c As Long
Dim aVal As String
Dim bVal As String
'Find Column in Row 1 containing word "Total Cost"
Worksheets("L2").Activate
Set HeadersRng = Range("A1", Cells(1, Columns.Count).End(xlToLeft))
TopCol = HeadersRng.Find(What:="Total Cost", LookAt:=xlWhole).Column - 1
BotRow = (Cells(65536, 1).End(xlUp).Row)
Col = Left(Cells(1, TopCol).Address(0, 0), 1 - (TopCol 26))

With Sheets("L2")
SourceArray = Range("A2:" & Col & BotRow).Value
End With

' Add a watch from the Debug menu and inset a break point to stop and
'check the values in the array in the Watches window


'Initialize SumArray Column "A". Number of Summary Rows is limited to 3

ReDim SumArray(3, TopCol)
SumArray(1, 1) = "A"
SumArray(2, 1) = "B"
SumArray(3, 1) = "C"

' Summarize SourceArray into SumArray
For i = LBound(SumArray) To UBound(SumArray)
For j = 1 To BotRow - 1
aVal = SumArray(i, 1)

bVal = SourceArray(j, 1)
If aVal = bVal Then
For k = 2 To TopCol
SumArray(i, k) = SumArray(i, k) + SourceArray(j, k)
Next
End If
Next
Next

'Write SumArray back in Sheets("L1") starting in Cell A10
For r = LBound(SumArray) To UBound(SumArray)
For c = LBound(SumArray, 2) To UBound(SumArray, 2)
Sheets("L1").Range("A10").Offset(r - 1, c - 1).Value = SumArray(r,

I did appreciate reading your solution like a brilliant move in Chess.
Now, I could come up with some convoluted and unesthetic SUM code
to have a Row and Columns Totals for r and c.
I could do it from the range, but what is the expert way of doing it
from the Array ?
In addition, for testing purpose I was trying to use Debug.print to
check the wole array after the last next.
But I get weird results in the immediate window.
This is the Debug.Print statement I used, and the syntax may in
error..
Debug.Print LBound(SumArray, 1), UBound(SumArray, 1), LBound(SumArray,
2), UBound(SumArray, 2)
Thank you again,
J.P.

Thank you again,

Here we go again.
The bottom Row had the right results but the SumCol did not.
I modified the last For Next as follows :
For k = 2 To TopCol
SumArray(i, k) = SumArray(i, k) + SourceArray(j, k) 'row sum
SumArray(4, k) = SumArray(4, k) + SourceArray(j, k) 'Column sum
SumArray(i, SumCol) = SumArray(i, SumCol) + SourceArray(j, k)
'Total Row Sum
SumArray(4, SumCol) = SumArray(4, SumCol) + SourceArray(j, k)
'Grand Total Row Sum
Next
and now I have the perfect summary, from Range to Array and back.
This was a major achievement for me, but I thank you again because you
put me back
in the right track in the first place.
..
The Debug.Print was only for testing purpose. I never saw my expected
values in the Immediate Window.
Where does Debug.Print send its data ?

Have a good day.
