Find replace using cells own row number

As a quick fix in a larger macro I am trying to replace the carried over "=#REF!*F and its its row number" with "D and its row number * F and and its row number"
I tried this but it gives a static reference to whatever cell is selected at the time

With Worksheets(2)
    LastRow = .Range("g" & Rows.Count).End(xlUp).Row
    Dim Findtext As String, Replacetext As String
    Findtext = "#REF!"
    Replacetext = "d" & Selection.Row ' does not give me the actual cells row number
    Columns("g8:g" & LastRow).Replace what:=Findtext, replacement:=Replacetext, lookat:=xlPart, MatchCase:=True
    End With

Any help appreciated
