I have 2 arrays that I have created in a macro. These arrays contain integer values and are 19x3 in size. The code to create the arrays is:

Workbooks(ResultsWB).Sheets("Daily Results - # Orders").Activate
Range("B5").Select
For j = 0 To 3
For i = 0 To 19
DailyArray(i, j) = ActiveCell.Offset(i, j).Value
Next i
Next j
Workbooks(CumWB).Sheets("Cum Order Data").Activate
Range("B5").Select

For i = 0 To 3
For j = 0 To 19
PrevCumArray(i, j) = ActiveCell.Offset(i, j).Value
Next j

The arrays are created correctly.

What I want to do, and can't seem to figure out the code to do it, is add the arrays together to create a third array (add the corresponding elements of each array). I am trying to do this in code using the array as a variable. If I want to create the third array as the values in a block of cells on a work sheet, using the "FormulaArray = " works,
With Selection
.FormulaArray = "=RC[-5]:R[19]C[-2]+'Cum Order Data'!R[-2]C[-5]:R[17]C[-2]"

but I then have to copy the results and paste them into the worksheet in a new place. I cannot create the array on the worksheet in its final location because I will be over-writing one of the arrays used in the formula.

Thanks in advance for the help

I'm not sure I'm following; aren't the arrays, which go from 0 to 19 and
0 to 3, 20x4 in size?

In any event, it looks like you're seeking:

Dim arr3(0 To 19, 0 To 3)
For i = 0 To 19: For j = 0 To 3
arr3(i, j) = DailyArray(i, j) + PrevCumArray(i, j)
Next: Next

For what it's worth, if the functions in the freely downloadable file at
http://home.pacbell.net/beban are available to your workbook, you could use:

arr3 = ArrayAdd(DailyArray,PrevCumArray)
