Running Value() Problem in S-Curve

Hi Everyone,

I have a dataset like below

X15ForecastsCounts X16ActualsCounts WeekEnding 38 18 7/23/07 38 14 7/30/07 38 35 8/6/07 37 NULL 8/13/07 37 NULL 8/20/07 37 NULL 8/27/07 37 NULL 9/3/07 36 NULL 9/10/07 36 NULL 9/17/07 22 NULL 9/24/07

I am plotting this data set as an S-Curve using the Running Value funtion.

The value and data point value is =RunningValue(Fields!X15ForecastsCounts.Value,Sum,"Series") similar code for X16Actuals Counts.

Unfortunately I am getting the curve like this http://tinypic.com/view.php?pic=4lyiuko

I dont want my X16ActualsCounts to extend beyond 8/6/07 in this case....and next week I dont want it to extend beyond 8/13/07.

How can I fix this issue?

Just to add more clarity to what I said above...I want the Running Value to stop calculating when it encounters NULL in the dataset.....If this is not possible ...Can I conditionally format the line curve...asking to color the line "Transparent" or "Maroon" based on a condtion....in this way my Actuals line will show until 8/6/2007...and the rest will be transparent.

Can someone please help me on this....
