I'm having issues with explosions not exploding.

[Qwertygiy]

Here's a really basic sample of the code I'm using:

[lua]
local tool = script.Parent

selectedz = false

function selected()
selectedz = true
while selectedz do
sleep(0.5)
e = create("Explosion")
e.Parent = game.World
e.Position = tool.Parent.Parent.Character.Body.Position
e.Radius = 15
e.Force = 3000
end
end

link(tool.Selected, selected)
[/lua]

Bomb tool of Jacob_'s works fine though.
