ActiveCell.FormulaR1C1 = "=R[-1]C[2] + 0 "

Try

Hi I am new to here, and have a question. I have figured out how I want
to
make the input box, but not how to incorpoarate the answer to my fomula.

What I need to do is add a cell address to a formula, but I need to change
the cell address to run different resaults.

What I have so far is very simple as I am trying to get it to work before
I
try it on the main workbook.
Res = InputBox("What is the cell address?")
If StrPtr(Res) = 0 Then
MsgBox "User Clicked Cancel"
ElseIf Res = vbNullString Then
MsgBox "User Clicked OK with no input"
Else
MsgBox "User Entered cell " & Res
End If
'
ActiveCell.FormulaR1C1 = "=R[-1]C[2] + 0 "
Range("D7").Select

Where 0 is I want to put the resualts of the cell I have just entered.
Any
suggestions? Thanks in advance!
