Trigger Help

[Unregistered]

Ok guys here's the deal. I currently have a sniper map in the works. I have some sounds in it that activate when each player earns a certain amount of lumber. Well you can only get lumber by killing other hero's. Since I can't set bounty as lumber, how can I make a trigger to give the killing hero 1 lumber per frag? I tried to select a unit but I clicked on my hero and it didn't do anything. Please help me I need help ahhhhhh.
