Hello, I have this (to me) strange situation:

Dim aRangeValues() As Double, aRangeDates() As Date

The two arrays are set to the foll. values (dates are in dd/mm/yyyy):

aRangeValues(1) | aRangeValues(2) | aRangeValues(3) | aRangeValues(4)
-1721.9482672 | 194.6875 | 194.6875 | 2194.6875

aRangeDates(1) | aRangeDates(2) | aRangeDates(3) | aRangeDates(4)
27/09/2002 | 30/09/2002 | 30/09/2003 | 30/09/2004



If I try to calculate the NPV (using XNPV - due to different intervals):
Val = Application.Run("XNPV", 0.05, aRangeValues, aRangeDates)
I get the #VALUE! error!

Just to check the situation, I tried to calculate:
Val = Application.Run("XIRR", aRangeValues, aRangeDates)
and I get a correct 0.262366098165512


I tried to use the XNPV function in a cell, and it works!

Any idea?

Thanks, Dario
