I'm not a VBA expert, and this is a very simple function...

I'm trying to create a function that will count the number of rows in
a named range. The function will be used in a formula in the workbook.

This is what I have:
-------------------------------
Function RowsInNamedRange(NamedRange As Range) As Integer

RowsInNamedRange = Range(NamedRange).Rows.Count

End Function
-------------------------------

When I test via immediate window using:
? RowsInNamedRange "rngNamedRange1"

Where "rngNamedRange1" is a named range. I get a type mismatch error.
I know this is a simple fix...but just haven't figured it out yet. Any
pointers??
