what's the problem with this ?
Function mySP(rng1 As Range, rng2 As Range, dec As Integer) As Double
Dim v As Double, IamTheCount As Long IamTheCount = rng1.Count mySP2 = 0 For i = 1 To IamTheCount v = Round(rng1.Cells(i, 1).Value * rng2.Cells(i, 1).Value, dec) mySP2 = mySP2 + v Next End Function So that if B1 thru C5 a 1.0234 0.45678 2.001 2.7 3.3 3 4.4 4 5.6543 5 then =mySP(B1:B5,C1:C5,3) will return 61.642 -- Gary's Student "dribler2" wrote: so short am i not to know the solution..never know the programming language. anyone know how to make this UDfunction work..
