I get an error, "Run-time error '1004': Application-defined or object-defined
error" when I run the following macro:

Sub Sheet_Names()
Dim ws As Worksheet
With Worksheets.Add
.Name = "Sheet Names"
.Move befo=Worksheets(1)
End With
Sheets("Sheet Names").Activate
Range("a1").Activate
For Each ws In Worksheets
If ws.Name < "Sheet Names" Then
ActiveCell.Formula = ws.Name
ActiveCell.Offset(1, 0).Select
End If
Next
End Sub

What does this error mean and how can I resolve it? The macro is supposed
to create a list of tab names in the workbook.

Thanks,

Dave
