I want to use the NETWORKDAYS function in VB. Here is what I have:

WrkDaysInMon=Application.WorksheetFunction.Network days(StartDate,FinishDate,
Worksheets("Lists").Range("V3:V24"))

In the spreadsheet body it works fine with:
=Networkdays(P4,R4,Lists!V3:V24)

When I try to use it in a macro, I get the message "Object doesn't support
this property or method"

What have I done wrong?

TIA
