AutoFilter with protected sheets

[ADK]

I have two sheets with autofilter. The code below works for the one sheet.
How can I list the two sheets in this code? Using Excel 2000Private Sub
Workbook_Open()
'check for filter, turn on if none exists
With Worksheets("Data")
If Not .AutoFilterMode Then
.Range("A1").AutoFilter
End If
.EnableAutoFilter = True
.Protect Password:="password", _
Contents:=True, UserInterfaceOnly:=True
End With
End Sub

sheet2: C6:I6
