Conditional Running Total

I have a crystal report where I am trying to do the following:

date              code             points calculated points      accum
04/26/13      TALP        0.5      0.5      0.5
04/29/13      TATD      1      1      1.5
04/30/13      TANN      0      5.5      7
05/01/13      TATD      1      1      8
05/02/13      TANN      0      1      9
05/03/13      TAUF      1      1      10
05/04/13      TALP             0.5      0.5      10.5

If the code is TANN, and the accumulated points are < 7, then the points to use for that TANN code are (7-accum), otherwise the points to use for the TANN code is 1.

It seems like I cannot have a running sum formula refer to itself.

Is there anyway to do this.  See attached example in an Excel file.
