problem with R1C1 Vlookup

Hi Guys, I have this Formula in an Excel tab.

Range("D" & Rows.Count).End(xlUp).Offset(1).Resize(10).FormulaR1C1 = "=VLOOKUP(RC[-3]&RC[-2], RC[3]:R[15]C[4], 2,0)"

It basically loops up from the bottom of Column D to hit the first populated cell, then goes down one row and inserts a Vlookup (RC[-3]&RC[-2], RC[3]:R[15]C[4], 2,0) and resizes it for the next 10 rows. However, I want to lock in the vlookup range so it remains the same range for the next 10 rows down.  How do I do that?

Try this.
Dim rw As Long

    With Range("D" & Rows.Count).End(xlUp).Offset(1)
        rw = .Row
        .Resize(10).FormulaR1C1 = "=VLOOKUP(RC[-3]&RC[-2], R" & rw & "C7:R" & rw + 15 & "C8, 2,0)"
    End With
