In case anyone is wondering why you can't use BRGlobals to share data between the XFBR/XFR_MemberList rule, and the DynamicCalc, is because the BRGlobals object gets destroyed between generation of the rows/column lists, and display of the data cells. Therefore we are forced to use SessionState in this particular case. You could however use BRGlobals to save the ranked list in the DynamicCalc once it has been retrieved. The use of a Shared variable achieves the same objective as using BRGlobals (but in a better way)
