Just checked for R1C1 formatting and the box was already unchecked. I do want to change out of this style of formatting if possible. If not, no big deal. I do however, need to make these references absolute because the current formula shifts the vlookup table down one row for everyrow that it is autofilled into. Example: Cell A1 can vlookup into range C1:D10 then cell A2 can vlookup into range C2:D11. I need A2 to have the ability to vlookup into A1. I hope that makes sense. If not, let me know and I will try to explain better. Thanks again for your help.
Range("W2").Select
ActiveCell.FormulaR1C1 = _
"=VLOOKUP(RC[-1],LOOKUP!R[1]C[-18]:R[113]C[-17],2)"
'Dim LR As Integer
LR = Range("A" & Rows.Count).End(xlUp).Row
Range("W2").AutoFill Destination:=Range("W2:W" & LR), Type:=xlFillDefault
Calculate
