How do you need the data displayed? In a column list like above, or all in a string? I am assuming that the dates are just for display purposes and not as parameters to gather the data.
you can build a string using a loop in a formula, something like:
shared stringvar dateList := "";
local datetimevar aDate;
aDate := {?startDate};
while aDate <= {?endDate}do{
dateList := dateList + ", " + totext(aDate, "MM/dd/yyyy");
aDate := DATEADD("d", 1, aDate);
}
I am not absolutely sure about the syntax, but you can look it up in Help.
