This is what I did so far,

Function GetCountryNames(Cell As Range) As String
Application.Volatile
Dim Countrys As String
Dim ws As Worksheet
Countrys = “”
Row = Cell.Row
Dim OCell As String
OCell = “O” & Row
For Each ws In Worksheets
If (ws.Name Worksheets(1).Name) Then
If (ws.Range(OCell).Value = “Yes”) Then
Countrys = Countrys & ” ” & ws.Name
End If

End If
Next ws

GetCountryNames = Countrys

End Function

I don’t know what wrong, but it isn’t working. Any help. Thanks

Actually INDEX is not a volatile function, even though some MSoft documentation says it is.

Anyway no its not possible to apply Application.Volatile(false) to a built-in Excel function except by duplicating what the built-in function does inside a UDF.

Application.Volatile(False)

to a volatile public function like INDEX and make it not volatile?

I suggest you do a dependency tree rebuild:

Everyone on the web can tell me about how to CREATE volatile functions, but I’ve just run into a case I hadn’t known about before. I have a standard, non-volatile spreadsheet with a ton of calculation going on (lots of array statements, GETPIVOTDATA statements, logic, etc.). I was then on the phone consulting with someone and wanted to test the NOW function and its response values. To test it locally, I picked an empty cell in my calc-intensive sheet and typed in =TEXT(NOW(), “mm/dd/yyyy”). Which worked fine and dandy, and was volatile (as I expected). So fine, no big deal, I go ahead and delete the value in that cell. Now here’s the kicker: Excel acts as if I STILL have a volatile function in the workbook, recalculating every time I change even the littlest thing. Needless to say, this is driving me crazy. Any ideas on how I can get my workbook to be non-volatile again (without changing my calculation settings)? Oy vey,

Caleb

Points out that INFO() is also volatile.
Includes other actions that trigger recalc.
