Hello
I am using the following code to hide/unhide rows:
Private Sub CommandButton1_Click()

Application.ScreenUpdating = False
Dim I As Long
Dim Hidden As Boolean
' For i = 14 To Cells(Rows.Count, "A").End(xlUp).Row
For I = 14 To 83
If Rows(I).EntireRow.Hidden Then
Hidden = True
Rows(I).EntireRow.Hidden = False
End If
Next I
If Hidden Then Exit Sub
' For i = 14 To Cells(Rows.Count, "A").End(xlUp).Row
For I = 14 To 83
If Cells(I, 1).Value < "BA" Then
' Range(Cells(I, 1), Cells(I + 9, 1)).EntireRow.Hidden = True
Rows(I).Hidden = True
End If
Next I
End Sub

This works fine up to 83 rows. I am trying to modify to use the last row
istead of hard coded row number. My attempts to modify (which arent working)
have been commented out. What am I doing wrong?
Thanks
