Need to find the right certificate to print based on fuel level

Hello dear ExcelForum, me again.

Need to find the right certificate to print based on fuel level at some date.

If i had 0 litres in reservoire and then 26Jan i received 30 000 litres, so in next days, if there isn't any other receive(in) i will print that(30000) certificate.
I need formula to somehow monitor fuel level. If fuel level is 31 000 litres at January 27th, something is wrong. If fuel level is 29 or less, then give customer that (30000) certificate. It's too complicated. Reservoires are 100 000 litres capacity, so there might be 130 000 receive in for some date(28 Jan), because, at 28 Jan i could also sell 30 000litres. It's so complicated.

Any help would be greatly appreciated.

What is a certificate?

You gave a bunch of specific examples, which are very confusing. (What does "something is wrong" mean? Why is something wrong just because the fuel level is 31,000 litres on January 27? What does "fuel level is 29" mean--29,000 litres? Why would you give a customer a certificate for 30,000 if they have 29,000 or less?) But you have not given us a set of rules to determine when a certificate should be printed.

The fact that you said twice that it's complicated suggests that you may not understand the business problem well enough yourself yet to explain what you need. The first thing is to explain what you are trying to do, and how you would do it if you didn't have Excel. Then we can explain how to do it in Excel.
