Because I am not real skilled at this, I understand what Option Explicit
means and that I have to dim certain pieces of code .. I do not know what to
dim as I'm getting an error for the rw in this code. Can someone help me
with this?

set rw = cells(rows.count,"F").End(xlup)

list = Array("DRH1", "DRH2", "DRH3", "DRI1", _

"DRI2","DRI3", "DRIA", "DRIB")

for i = rw to 1 step -1

res = Application.Match(cells(rw,"F").Value,list,0)

if not iserror(res) then

cells(rw,"F").EntireRow.delete

end if
