You Killed the Creator Badge?

So I was trying to see if I could script one, but when I test it with someone else it seems not to award the person who killed me. Any thoughts on the code below? I never really tried to see who killed who. IF someone could help I would appreciate it.

Error: None

Code:

game.Players.PlayerAdded:connect(function(plr)
plr.CharacterAdded:connect(function(char)
char:WaitForChild("Humanoid").Died:connect(function()
if char:FindFirstChild("creator") and char.creator:IsA("ObjectValue") then		
if plr.Name == "DevFrank" then
local killer = char.creator.Value
game:GetService("BadgeService"):AwardBadge(killer.userId,  0) --0 is an example
end
end
end)
end)
end)

Just put a little script in the kill script that says something like 'if damagedplayersname is devfrank then award the badge to the killer using the badgeservice'

I'm not sure, that's how I've been taught to use this.
