I see what you mean Tom.
Nevertheless, I cannot see the reason for that original error.

The original working code sequence was:

For ColNdx = 5 To 9 'cols E to I
Cells(EndToCollectionRow - 1, ColNdx).FormulaArray = "=SUM((" & Range( _
Cells(StartToCollectionRow, "C"), Cells(EndToCollectionRow - 2, "C"))
_
.Address & ")*(" & Range(Cells(StartToCollectionRow, ColNdx), _
Cells(EndToCollectionRow - 2, ColNdx)).Address & "))"
Cells(EndToCollectionRow - 1, ColNdx).Value = _
Cells(EndToCollectionRow - 1, ColNdx).Text
Next ColNdx
which produced that error of which I originally posted.

With Alex's help I tried to implement the Round function within the above
FormulaArray expression, as follows:

For ColNdx = 5 To 9 'cols E to I
Cells(EndToCollectionRow - 1, ColNdx).FormulaArray = "=SUM(ROUND(" &
Range( _
Cells(StartToCollectionRow, "C"), Cells(EndToCollectionRow - 2, "C")) _
.Address & ")*(" & Range(Cells(StartToCollectionRow, ColNdx), _
Cells(EndToCollectionRow - 2, ColNdx)).Address & "), 2)"
Cells(EndToCollectionRow - 1, ColNdx).Value = _
Cells(EndToCollectionRow - 1, ColNdx).Text
Next ColNdx

Can this be achieved, please?

Regards.

What kind of testing have you done Stuart?

Sub Tester9()
starttocollectionRow = 1
Endtocollectionrow = 8
colndx = 3
sStr = "=SUM(ROUND(" & Range( _
Cells(starttocollectionRow, "C"), Cells(Endtocollectionrow - 2, "C"))
_
.Address & ")*(" & Range(Cells(starttocollectionRow, colndx), _
Cells(Endtocollectionrow - 2, colndx)).Address & "), 2)"
Debug.Print sStr
End Sub

produces

=SUM(ROUND($C$1:$C$6)*($C$1:$C$6), 2)

so you have clearly miscoded it since this formula is in error.

Have amended to:

For ColNdx = 5 To 9 'cols E to I
Cells(EndToCollectionRow - 1, ColNdx).FormulaArray = "=SUM(ROUND(" &
Range( _
Cells(StartToCollectionRow, "C"), Cells(EndToCollectionRow - 2,
"C"))
_
.Address & ")*(" & Range(Cells(StartToCollectionRow, ColNdx), _
Cells(EndToCollectionRow - 2, ColNdx)).Address & "), 2)"
Cells(EndToCollectionRow - 1, ColNdx).Value = _
Cells(EndToCollectionRow - 1, ColNdx).Text
Next ColNdx

and get "Unable to set the FormulaArray property of the Range class"
error.

Did I miscode your suggestion?

Regards and thanks.

Thanks, but I think the chance to Round has passed by the time
the value hits the Sum cell.
I guess I need to find a way to Round each calculation BEFORE
its' result is added to the Sum....if you see what I mean.

Sorry Stuart,

round globally the product this way

....formularray = SUM(ROUND(array1*array2;roundoff))

Choose the round off you desire.

I tested this formula manually in a worksheeet and Excel allows it.

Let us know.

Alex.
