interval type

iI took some of cathy's ideas but it is just not quite right. can someone explane what is happening here. The group values work great, but the grand totals does not. The group values print but the grand total is blank. rpt.callduration is an interval hour to second define rpt record like callrecord.*, calldur interval hour to second, call5 interval hour(5) to second, call7 interval hour(7) to second, ucallsum interval hour(5) to second, tcallsum interval hour(7) to second, ucnt integer, tcnt integer [...] on every row let calldur = rpt.callduration let call5 = calldur let call7 = calldur after group of rpt.username let ucallsum = group sum(call5) let ucnt = group count(*) print column 1, rpt.username, column 20, ucnt, column 35, ucallsum, column 55, ucallsum/ucnt on last row let tcallsum = sum(call7) let tcnt = count(*) print column 1, "GRAND TOTALS", column 20, tcnt, column 35, tcallsum, column 55, tcallsum/tcnt [...] Bert
