Spaghetti, I�m wondering whether you�ve identified the five �different� elements correctly?? If so, you should be able to reach a unique, logical conclusion.
I�m a newcomer to the site too, but from the threads that I�ve read, there are different tolerances for the degrees of help sought and given! In my view, your question and my response are both perfect etiquette :-) .. but others would perhaps go further and some will no doubt be getting tetchy already! Basically I think a good hint should be sufficient to confirm that something�s not quite right, helpful in terms of suggesting the area for further exploration, but insufficient to give the game away.
