Breaking door in touch tool script,Battering ram?

Thats the script,it dont works and i dont know why,Anything is wrong? Its a normal script into a part of a tool.

local debounce = false 
dir = math.random(2)

function onTouch(part) 
if script.Parent.Parent.Swing.Value == true then
	if part.Name == "Door" then
			
					sund = Instance.new("Sound",part)
					sund.SoundId = "http://www.roblox.com/Asset/?ID=158712406"
					sund.Volume = 2
					sund:play()
					part:BreakJoints()
					part.Anchored = false
					part.CanCollide = false
					part.Velocity = part.CFrame.lookVector *10
			
					
				
			end
		end

wait(1) 
debounce = false 
end 



script.Parent.Touched:connect(onTouch) 

debounce = false
dir = math.random(1,2)

script.Parent.Touched:Connect(function(part)
	if debounce == true then
		return
	else
		if script.Parent.Parent..Swing.Value == true and part.Parent.Name == "Door" then
			local sund = Instance.new("Sound",part)
			sund.SoundId = "rbxassetid://158712406"
			sund.Volume = 2
			sund:Play()
			for i,v in pairs(part.Parent:GetChildren())
				v.Anchored = false
				v.CanCollide = false
				for e,p in pairs(v) do
					if p:FindFirstChild("WeldConstraint") then
						p:Destroy()
					end
				end
				v.Velocity = v.CFrame.lookVector * 10
			end
		end
	wait(1)
	debounce = false
	end
end)

Breakdown of the script:

math.random(1,2)

math.random() needs a minimum and maximum value to calculate between.

script.Parent.Touched:Connect(function(part)

When an object touches the script's parental object, it will identify that object with the parameter called "part" for the function (not the entire script).

if debounce == true then
	return
else

When the variable is fired already, it will not trigger again until the variable debounce is equal to false.

if script.Parent.Parent..Swing.Value == true and part.Parent.Name == "Door" then

If both of these variables are what they should be, then the function will continue. Otherwise, it will not continue until both of them are what they should be.

Assuming that the script's parental object touched a part that is inside a model, I added part.Parent to get the model name instead. You can change this back if the part is not in a model, or if you are looking for a part inside a model.

for i,v in pairs(part.Parent:GetChildren())
	v.Anchored = false
	v.CanCollide = false
	for e,p in pairs(v) do
		if p:FindFirstChild("WeldConstraint") then
			p:Destroy()
		end
	v.Velocity = v.CFrame.lookVector * 10
	end
end

For every part in the model, it will unanchor, make uncollideable, and then later, have the part fly towards it's lookVector.

The velocity may not be what you want it to be, because if the lookVector of a part is facing towards the battering ram, it will fly that way instead. To fix this, you just have to reface each part towards a direction.

For each item's class named "WeldConstraint", it will destroy that. You may change this to whatever fits your game, but since it is a door, I assumed that it is a WeldConstraint.

wait(1)
debounce = false

After it is done with destroying each constraint, it will let anything else fire after 1 second.

Let me know how it goes. If possible I'd like to test it as well if you'd like.
