How to set an offset value in a range

I'm trying to copy data from column B to column AO if column C meets a condition. My problem is I don't know how to set the result value. (non-programmer)

Sub MoveSubDescToAtt()

   For Each Cell In Range("C:C")
      If Cell.Value = "[No Product Description]" Then
       Cell.Offset(0, 38) = "I need this cell to equal the contents of what's in column B, same row) 

      End If
    Next

End Sub

Thank you in advance.
