property for the range class.

i'm getting this error on the line 37.

here is my code. kindly help me at the earliest.

Workbook Open code:-

Dim I As Integer
Dim J As Integer
Dim LastLine As Integer
Private Sub Workbook_Open()

For I = 4 To 500
If Sheet6.Cells(I, 1).Value = "-" Then
LastLine = I
'MsgBox LastLine
Exit For
End If
Next I

Sheet6.Unprotect Password:="123"

Sheet6.Cells(1, 6).Value = Date
Sheet6.Range(Cells(1, 1), Cells(2, 256)).Locked = True

For I = 3 To LastLine - 1
Sheet6.Cells(I, 7).Locked = True
Next I

For I = 3 To LastLine - 1
For J = 9 To 38
Sheet6.Cells(I, J).Locked = True
Next J
Next I



For I = 3 To LastLine - 1
For J = 9 To 13
If Sheet6.Cells(I, 8).Value = "" Or Sheet6.Cells(I, 8).Value =
"NR" Then
Sheet6.Cells(I, J).Locked = True
Else
Sheet6.Cells(I, J).Locked = False
End If
Next J
Next I

For I = 4 To LastLine Step 2
Sheet6.Cells(I, 9).Locked = True
Sheet6.Cells(I, 10).Locked = True
Next I


Sheet6.Range(Cells(3, 39), Cells(LastLine, 256)).Locked = True
Sheet6.Range(Cells(LastLine, 1), Cells(65536, 256)).Locked = True

Sheet6.Protect Password:="123", AllowFiltering:=True
