Debounce not working?

coroutine.resume(coroutine.create(function()
local t = false
while wait() do 
wait()
if down == true then
repeat wait() until down == false 
stik2 = stik:Clone()
stik2.Parent = game.Workspace
stik2:BreakJoints()
stik.Transparency = 1
stik2.CFrame = CFrame.new(stik.Position)
stik2.Touched:connect(function(hit)
if hit then
vol:Destroy()
hum = hit.Parent:findFirstChild("Humanoid")
if hum and hit.Parent.Name ~= plyr.Name then
if t == false then
t = true
hum:TakeDamage(99)
t = false
end
end
end
end)

t is the debounce, i want it to do 99 damage, but it just kills.
