I need to compare the two list box's selected items and populate a third list box with the difference of the first two . Say : List A has items 1,2,3 checked and List B has just 2,3 checked . So i would like to have List C to be populated with the Difference of A,B = 1 Is this possible with any filter conditions ? Please help . Regards, Grigory
