Spawn a prefab

Hi again, I am a noob at unity and javascript, but so far I have had some luck regarding this project I am experimenting with; however, that luck has run out. I have been trying to figure out how to spawn a prefab particle after it has been destoryed, but to no avail have I succeeded. Help would be greatly appreciated. And if someone could also tell me how to show my java script thing on this site, would be greatly appreciated.


Right up the top it say Harness Object None. Assign a GameObject or prefab here by dragging one in. Then it will work
