Add the summary field a second time, again using a sum. Then select the inner cells (for days)->right click->format field->suppress. In design mode, resize the suppressed summary to minimize the height, by drawing the bottom border up.
Next select the newly created second summary in the total row, and right click->format field->suppress->x+2->and enter:
whileprintingrecords;
numbervar x := x + currentfieldvalue;
false
Then in the same format screen, select "Display String"->x+2 and enter:
whileprintingrecords;
numbervar x;
totext(x,0,"")//0 for no decimals, "" for no comma divider
You can also edit the "Total" label by adding a return and entering "Cumulative".
