Hi I am try to set it up on a risk register when to review their actions at a
certain date after the actions have been set, initially I was under the
impression it was always the month after but have since found out it is more
complicated than this:

Action Date Review Date
November December
December or January February
February March
March or April May
May June
June or July August
August September
September or October November

I have been messing around with an IF function along the lines of
=IF(AND(J17="December",J17="January"),"February",I F(J17="November","December",IF(J17="February","Mar ch",IF(AND(J17="March",J17="April"),"May",IF(J17=" MAY","June",IF(AND(J17="June",J17="July"),"August" ,IF(J17="August","September",IF(AND(J17="September ",J17="October"),"November")))))))

But this isn't working so I was wondering if there was a simpler way of
doing it?
