If Cell.Value= "test" Fill Range with colour

Hi, I've named range C1:X1 as RANGE
What i need is excel to seach the range for values equals to test and then shade the cell from the active cell to the cell 10 rows below. Currently my code is like this :

Sub ChangeColor()

    Dim rCell As Range

    With Sheet1
        For Each rCell In .Range("RANGE").Cells
            If rCell.Value = "Test" Then
                rCell.Interior.ColorIndex = 15
                rCell.Select
                Selection.AutoFill Destination:=Range("???"), Type:=xlFillFormats
            End If
        Next rCell
    End With

End Sub

Anyone know what should I replace with the Range? Thanks in advance. I'm using excel 2003 by the way.
