On the Revenue Summary tab when I changed from ƒ??This calendar yearƒ? to ƒ??Last calendar year,ƒ? it began processing and returned the ƒ??Household summaryƒ? but took a while to return the ƒ??Individual summary.ƒ? It appears as soon as you make a change on any parameter, it starts to recalculate. It seems it would be more efficient to have the ƒ??Refreshƒ? button, so that one could make all the changes before recalculating.
