Stop a Running Total

I have a simple running total (0% to 100%) calculated from a series of monthly progress values. The number of months where progress is made varies within a set range of months, let's say its a 32 month project and the first progress value is in the 3rd month and it reaches 100% in the 24th month. If I have to select all 32 months to chart, how do I get the 0% months and all the 100% months after the first month with 100% to give me a #N/A? I have multiple rows with running totals all varying in start and finish months that need to be plotted as S-Curves and I only want to show the curves up to the first 100% value in each row.

Excel Facts

Square and cube roots
The =SQRT(25) is a square root. For a cube root, use =125^(1/3). For a fourth root, use =625^(1/4).
assuming that you're calculating these things, something like:

-if(or(progress=0,progress=1),na(),progress)

...where 'progress' is whatever formula you're using.

edit - just noticed that the above will mask the point where you first hit 100%.

im in a rush, so inelegant solution - assuming, e.g., you had a row of raw values from a2:a20, with the cumulative progress in col b, then in c2, copied down:

...if(or(b2=0,b1=1),na(),b2)

...then chart off that. using b1 in the second condition for the or() (i.e. the cell before your data starts) serves to make sure you include the first instance of 100%

Thanks for the response. This worked great! When I first read it, I thought to myself, no, this is what I have already tried. ...but then I realized you were referencing the source data in all instances. I however had been referencing the previous cell from the formula I was writing. Which gave me all #N/A results, due to the previous cell being #N/A. Thanks so much for the resolution.
