Hello again, Loredana. Additional information required :-) imagine the following situation 1| LIA | recv1 | date1 | (date1,date2) 2|LIA | recv1 |date 1 | (date2,date3) 3| LIA | recv1 | date1 | (date1,date3) Should this yield 6? Or 4?
date 1 is not on the second dates column, but it is on the remaining two
if the first column is count then the sum(count) should be 4. Loredana
