Running Total reset by negative value

[Neil_R]

I am trying to setup a spreadsheet to track a number of values. I only need to create a running total when the total of 2 columns becomes a positive value and then track it back down to when it moves back to a negative. The data looks like this:

[TABLE="class: grid, width: 500, align: center"]
<tbody>[TR]
[TD]Value A[/TD]
[TD]Value B[/TD]
[TD]A + B[/TD]
[TD]Required Result[/TD]
[/TR]
[TR]
[TD]0[/TD]
[TD]-2000[/TD]
[TD]-2000[/TD]
[TD]0[/TD]

[TD]-3500[/TD]

[/TR]
[TR]
[TD]0[/TD]
[TD]-5300[/TD]
[TD]-5300[/TD]
[TD]0[/TD]
[/TR]
</tbody>[/TABLE]
I feel like there is an easy solution that I am just missing by nesting IF loops or something along those lines, I have tried with extra columns but I am missing something. Creating a running total isn't hard but having it reset is the problem.

Any ideas are gratefully received!

Try this

Re: Running Total reset by negsative value

Edit:

Use this formula:

=IF(AND(IFERROR(VALUE(D1),0)=0,C2<0),0,IF(IFERROR(VALUE(D1),0)>=0,IFERROR(VALUE(D1),0)+C2,0))

And just like that, problem solved. Thanks, I was coming at it from the wrong angle!
