[Excel] 2003 vs 2007 - Range functions

[datapard]

This works in 2000/2003, unfortunately I'm getting

Run-time error '438':
Object doesn't support this property or method.

The code is below.

Sub cleanData()
'
    Dim rng As Range
    Dim lLastrow As Long
    
    Selection.AutoFilter
    ActiveSheet.UsedRange
    lLastrow = ActiveSheet.Cells.SpecialCells(xlCellTypeLastCell).Row
    Set rng = Range("J2", Cells(lLastrow, "J"))
    ActiveSheet.rng.AutoFilter Field:=10, Criteria1:=Array( _
        "Key Target", "Dead", "Lead", "Won", "="), Operator:=xlFilterValues
    rng.SpecialCells(xlCellTypeVisible).EntireRow.Delete
    Range("A1").Select
    Selection.AutoFilter
End Sub

The following is were the code appears to break.

ActiveSheet.rng.AutoFilter Field:=10, Criteria1:=Array("Key Target", "Dead", "Lead", "Won", "="), Operator:=xlFilterValues

Since the file will never have a set number of rows, I really need to be able to set the range on the fly. This office has both 2003 and 2007 and appears to be converting slowing to being all 2007, which means that the macro packet I build for them has got to run cleanly in both. Any suggestions.
