I've got two words good + luck :lol: Mine have never quite got the hang of it, although i am going to make a concerted effort again next week once i've got some trays. Seriously though, they do like to much hay while they're on the loo, so get a nice big tray(s) - i was recommended the underbed storage boxes, i saw some on tescos website yesterday - and make sure there is some hay in it or in a rack right next to it. Also, as far as weewees are concerned they tend to go in corners and in the same places so if you see them favouring a particular spot then pop a tray there. It is also much easier after neutering/spaying as there's less territory marking pooping.
