Peter,

I think you are making this too complicated. It looks light it can be done much more simply if the following assumptions hold true:
1. 90 day period is actually 60+, meaning up to and after ninety. If not, you need an A90gr variable, for greater than ninety days
2. There is no detail available, and you are dealing with totals per period only.

Therefore, the following code gives you a cursor to feed to the report:

SELE CustomerCode,;
     C30 - P30 AS A30,;
     c60 - p60 AS A60,;
     C90 - P90 as A90,;
     p30 + p60 + p90 as "PT";
  FROM MySummedResults;
  INTO CURSOR ReadyForResult;
  ORDER BY CustomerCode

>I need to add an account aging set of columns to an existing detail report. I believe I have the formulas but am not sure how to get the information into the cursor (or from the cursor) that is used to generate the report...
