That is the formula that I used. So not quite understanding your question. When I use that formula..I get the results I posted in the post.. For December I get 1, until the date is beyond 30 days then it becomes 2... I need it to just look at the month, not count by days.. so if you were to take this month... then December 2013 would be 1 month back, November 2013 would be 2 months back etc.
