Hi! This seems oh so simple and it works when I 1st use this function in a
cell formula, but upon closing and re-opening the spreadsheet (Excel 2003)
it gives me a Name error everwhere I used this function!

The function's purpose is to count up and return the number of cells in a
Named Range that don't have a grey background color. I need this information
in a percentile function to calculate the percentage of completion for
different sections on a spreadsheet. It works right, but only when I 1st
enter the function in my percentage of completion cells.... later after
restarting the spreadsheet, it no longer works. What's up with that?

Below is the function:

Public Function CountCells(MyCells As Range) As Integer

Dim MyCell As Range
Dim ctr As Integer

For Each MyCell In MyCells
' Only count the Clear background, White background, or Yellow
background cells
If MyCell.Interior.ColorIndex = -4142 Or MyCell.Interior.ColorIndex
= 2 Or MyCell.Interior.ColorIndex = 19 Then
ctr% = ctr% + 1
End If
Next
Set MyCell = Nothing
CountCells = ctr%

End Function


And it's used in cell's with the following formula:
=C89/CountCells(GreenSection1)

GreenSection1 being a named range of cells and C89 being a cell with a
number in it. There's ALOT of formulas of this nature in this spreadsheet
though, this is only an example of how I'm using the UDF.

Can anybody explain why this only works when I input the formula (with UDF)
into a cell, and then no longer works once the spreadsheet has been
restarted? Is there any other way to accomplish what this UDF is trying to
do with built-in Excel functions instead?

Right now I'm having to go thru and manuall count up the cells and hard-code
the number into my formulas, and MAN oh MAN is this tedious!!! Plus it's not
very maintainable, if we add or remove rows from the spreadsheet the numbers
will need to be manually updated again. Ughhhh! 8-(

Thanks!
