Hi,
I have three multi select list boxes containing same number of items. 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
