Excel VBA Public Sub call to delete files is not working

I have some vba code in Excel (2010) that exports each sheet into a separate csv file.  This works well.  Then I have created a sub that I try to call at the end of the process which will delete only one of the csv files.  It works when I run the delete file sub directly, but when I call it it does not delete the file.   There are 9 files created and I just want to combine 8 of them, so I want to delete the “Summary” file before I combine them (I know I could exclude it from being exported, but I still need the solution since I want to delete all of the individual files, after they have been combined.  (I have not created the code to combine the files yet.  I have s simple bat file that works well, I plan to call that).

Private Sub SaveAllSheetsAsCSV()
On Error GoTo Heaven
' This creates multipls csv files
' each sheet reference
Dim Sheet As Worksheet
' path to output to
Dim OutputPath As String
' name of each csv
Dim OutputFile As String

Application.ScreenUpdating = False
Application.DisplayAlerts = False
Application.EnableEvents = False

' ask the user where to save
OutputPath = "C:\temp"

If OutputPath <> "" Then
     ' save for each sheet
    For Each Sheet In Sheets
        
    OutputFile = OutputPath & "\" & Sheet.Name & ".csv"
    ' make a copy to create a new book with this sheet
    ' otherwise you will always only get the first sheet
    Sheet.Copy
    ' this copy will now become active
    ActiveWorkbook.SaveAs Filename:=OutputFile, FileFormat:=xlCSV, CreateBackup:=False
    ActiveWorkbook.Close

    Next
    End If

Finally:
    Application.ScreenUpdating = True
    Application.DisplayAlerts = True
    Application.EnableEvents = True
    Exit Sub

Heaven: MsgBox "Couldn't save all sheets to CSV." & vbCrLf & "Source: " & Err.Source & " " & vbCrLf & "Number: " & Err.Number & " " & vbCrLf & "Description: " & Err.Description & " " & vbCrLf
