I would like to see that I am continually saving on a per-day basis (as well as overtime). I allowance myself an allowance each day, but some days, I need to spend more money than that. The best solution I have to is keep a running total for myself, so that each day is affected by the preceding days. Therefore, if I spend too much, I now have a small defecit that needs to be corrected. This method keep me on track as far as saving and spending.

Question (and I copied the actual data from my spreadsheet):

Without having to manual enter the final calculations (because this is just a simple part of an overall larger, more complex spreadsheet), can I generate the values in my Value Change row, based on the information from my Running Total row?

For example, Day 1 to Day 2, I was able to incease my running total from 233 to 354 (meaning that I had saved +121 that day). Of course, this is an easy subtraction problem (Day 2 - Day 1 = Value Change). From Day 2 to Day 3, I spent way too much. The running total fell to -1198, meaning that I spent 1552 too much (that day's value change is -1552). Again, this an easy subtraction (Day 3 - Day 2 = Value Change, just like the first example). From Day 3 to Day 4, I was able to reduce my running total -1063, meaning that I was able to save 135 that day. This is my problem. Day 4 - Day 3 does not equal the value change of + 135. To get this value, the preceding formula now has to change to ABS(Day 3) - ABS(Day 4).

This is the issue. I need a formula that can work normally when the numbers are postive or when the second value is larger (in terms of absolute value). On the other hand, it needs to recognize the special cases like Day 3 - Day 4. Is this some form of a conditional function?
