I have one list with all the elements(list1) and a second one with the selected ones(list2). I need i third one with the NOT SELECTED(list3), like list3=list1-list2. I created a hidden field with the selected ones(2 fields are the keys this is list2) and built a list with all the possible values getting two column2 of a view(list1). So, i get each list2 value and check if it is in list1, if it’s not, it goes to list3, if it is i get the next one. It’s too slow, can someone geve-me a clue how to do it more quickly?Thanks in advance,
