[quote:2n1epmg8]of those objects, Pick those that are flammable
But your not doing that. There's no exclusivity, all your doing is adding to the pile, each sub event is just like saying then... do this.
Like if I said choose the two marbles next to each other, then I said choose all the marbles that are within the circle.
In order for your logic to work you would have to add an event to drop any that weren't next to each other.
Or strangely enough place both picking conditions into the same event, rather than separate events. In order to understand how that works you have to think in terms of the conditions rather than the events. Having two conditions like that is like saying "of those", basically and rather than then.
Remember there are two parts to an event, the condition(s), and the action(s).
Hope that makes more sense, and that last parts probably going to confuse the heck out of you.
If your still unsure, I would suggest doing a google for Boolean, and logic operators.
