Thanks for any help.
I have some code in my macro:
dSum = Application.Sum(Selection.SpecialCells(xlVisible))
but if there is nothing selected (at least visibly selected), I get an error
"Run-time error '1004': No cells selected."
Is there some kind of IF, like IF (Application.Sum...)=NULL or something so
my program doesn't terminate?
Thanks

Try this..

Dim rngToSum As Range
Dim dSum As Double

Set rngToSum = Selection.SpecialCells(xlVisible)

If rngToSum Is Nothing Then
dSum = 0
Else
dSum = Application.Sum(rngToSum)
End If

One way is to test the Selection.

If TypeName(Application.Selection) = "Nothing" Then
'No selection was made
Else
'Perform work on selection
End If

I think you'll have to watch out for the error:

Option Explicit
Sub testm()

Dim rngToSum As Range
Dim dSum As Double

Set rngToSum = Nothing
On Error Resume Next
Set rngToSum = Selection.SpecialCells(xlVisible)
On Error GoTo 0

If rngToSum Is Nothing Then
dSum = 0
Else
dSum = Application.Sum(rngToSum)
End If
End Sub

======

Another option (I like Jim's better):

dSum = 0
on error resume next
dSum = Application.Sum(Selection.SpecialCells(xlVisible))
on error goto 0
