Debounce does not work as intended with .Touched event?

Currently trying to make a combat system with .Touched and having trouble "debouncing" with the event.

script.Parent.Activated:Connect(function()
	if not debounce then
		debounce = true
		if combo == 0 then
			combo = 1
			newHitbox = hitbox:Clone()
			newHitbox.Parent = myHumanoidRootPart
			newHitbox.CFrame = myHumanoidRootPart.CFrame
			debris:AddItem(newHitbox, 0.9)
			
			local weld = Instance.new("Weld")
			weld.Parent = newHitbox
			weld.Part0 = newHitbox
			weld.Part1 = myHumanoidRootPart
			
			newHitbox.Touched:Connect(function(hit)
				if hit.Parent:FindFirstChild("Humanoid") then
					print("Hit")
				end
			end)
			
			combo = 0
		end
		debounce = false
	end
end)

I've tried adding a debounce within the touched event itself and that didn't work either.

It'll essentially detect all the players' body parts pritning "Hit" 7 times rather than 1.

To build upon what Crimsonicacy said, you need to add a wait to it because as soon as the event fires, you're setting it to true then immediately back to false. Also, however, you need to move the debounce into touched event itself, or setup a second for the touched event, as the debounce outside of it won't have any effect on it as is meaning it is still reading it as every single part that touches it will pass through.
