Find difference between 2 rows

Hi, 

AlexisOlson Yes, it is. I could not reproduce your results before opening your attachment, because I simply regarded [Gen Hours] in your formula as a column. I found it after I just opened the attachment.
I think what axk180022  might need is a column. I took this as a challenge and got the above formula.

Hi, axk180022 , I believe that the solutions provided by AlexisOlson speedramps  are all workable, and I hope these are useful to you.
