My debounce doesn't work and there is no delay?

The debounce just doesn't work, there is no delay in how fast points are distributed. (yes the script could be shorter but it's my first script)

function givePointss(hit)


 local debounce = false
 local thevehicle = hit.Parent
 local daseat = thevehicle:FindFirstChild("VehicleSeat")
 local p = daseat.Occupant
 local player = p.Parent
 local daplayer = game.Players:GetPlayerFromCharacter(player)
 local coins = daplayer.leaderstats.Coins
if debounce == true then return end 
  debounce = true
  coins.Value = coins.Value +1
  wait(5)
  debounce = false
 end
script.Parent.Touched:connect(givePointss)

the debounce should be defined out of the function not inside of it
