How to use functions properly

[MuhammadZiaUrRehman]

Hi, My name is Muhammad and I am working in Pakistan Petroleum. I am making a policy model for my seniors. During the work, I encountered a problem with the formula making in excel. I have given a table below. what I need to do is build a model for the bonus amount that has to be taken from first table of Cumulative Production and Amount Columns. The model says that upon reaching first 90 days of start of commercial production, the one time bonus to be given is 400000. and then upon reaching a certain level of production like 60 MMBOE, 120 MMBOE ,160 MMBOE and 200 MMBOE, we need to give corresponding one time amount of bonus in form of 1600000, 3000000, 9000000,and 12000000. However this amount will not be paid annually but just one time. If function gives the amount but what it does is that it puts the bonus in the next years as well which is not required. Like if we reach 60 MMBOE in 2019 and 80 MMBOE in 2020, then the amount should reflect only in the cell corresponding to 2019 not in 2020 where it should be zero. and then upon reaching or crossing 120 MMBOE next amount should show and so on. If anyone can help me in this regard as to what kind of formula can be applied to do it what kind macros can be written to do it, it will be very helpful for me and I will be very thankful. Or if it can be done only manually, then also please do tell. thank you
I have also attached a file .

Cumulative Production Amount Cumulative MMBOE Year Bonus
90 days 400,000 2017
60 MMBOE 1,600,000 2018
120 MMBOE 3,000,000 2019
160 MMBOE 9,000,000 2020
200 MMBOE 12,000,000 2021



Some one helped me by applying Max function but I want the 1st bonus that gives at start of production that is where the cumulative production first becomes non zero also to be incorporated. please if anyone can help me out in this regard , i will be really grateful
