OK, so I did something like this and the procedure displays only As in block c. Please show me where is the mistake.
* Pick 4 items at random onexptbegin and store item numbers in list.chosenitemslist *
<expt>
/ onexptbegin = [list.chosenitemslist.setitem(list.allitemslist.nextvalue, 1);
list.chosenitemslist.setitem(list.allitemslist.nextvalue, 2);
list.chosenitemslist.setitem(list.allitemslist.nextvalue, 3);
list.chosenitemslist.setitem(list.allitemslist.nextvalue, 4);
list.chosenitemslist_1.setitem(list.allitemslist.nextvalue, 5);
list.chosenitemslist_1.setitem(list.allitemslist.nextvalue, 6);
list.chosenitemslist_1.setitem(list.allitemslist.nextvalue, 7);
list.chosenitemslist_1.setitem(list.allitemslist.nextvalue, 8);
