With ActiveWorkbook
.Names.Add Name:="ArrTemp", RefersToR1C1:="={1,2,3,4,5,6,7,8,9,10}"
.ActiveSheet.Cells(1, 1).Value =
Evaluate("=SUMPRODUCT(--(ArrTemp=1),--(ArrTemp<=5))")
.Names("ArrTemp").Delete
End With
End Sub


2) does not work

With ActiveWorkbook

A = 1
B = 2
C = 3
d = 4
E = 5
F = 6
G = 7
H = 8
I = 9
j = 10

..Names.Add Name:="ArrTemp", RefersToR1C1:="={A,B,C,D,E,F,G,H,I,J}"
..ActiveSheet.Cells(1, 1).Value =
Evaluate("=SUMPRODUCT(--(ArrTemp=1),--(ArrTemp<=6))")
..Names("ArrTemp").Delete
End With

thank you
