Unable to make certain tagged parts unanchor when a specific part touches them

Help and Feedback Scripting Support
#1

I am an early intermediate level scripter, and I am currently trying to make a game for fun, and to practice, I have run into a problem where I am unable to make certain tagged parts unanchor when a specific part touches them, this script has no red underlined sections, or causes any errors, any help would be appreciated!

task.wait()
local Tornado = workspace.Tornado
local CollectionService = game:GetService("CollectionService")
local canbedestroyed = CollectionService:GetTagged("canbedestroyed")


for _,Part in pairs(canbedestroyed) do
	Part.Touched:Connect(function(hit)
		local Strength = Part:GetAttribute("Strength")
		local mph = workspace.torado:GetAttribute("mph")
		if hit == Tornado then
			if mph > Strength then
				Part.Anchored = false
			end
		end
	end)
end

this has a pretty common memory leak in it, remember to disconnect connections on parts when they’re destroyed or not needed anymore:

--pro tip: "for ... in  t" is legal and slightly faster than "pairs()"
for _,Part in canbedestroyed do
	--this is a type annotation, it helps out with autocomplete and they're really useful
	local onTouched:RBXScriptConnection, onDestroying:RBXScriptConnection
	onTouched = Part.Touched:Connect(function(hit)
		if hit == Tornado then
			local Strength = Part:GetAttribute("Strength")
			local mph = workspace.torado:GetAttribute("mph")
			if mph > Strength then
				Part.Anchored = false
				onTouched:Disconnect()
				onDestroying:Disconnect()
			end
		end
	end)
	--:Once() is identical to :Connect(...) except that the connection is disconnected when fired
	onDestroying = Part.Destroying:Once(function()
		onTouched:Disconnect()
	end)
end

apart from that, maybe the loop is being executed before the parts exist so try binding a function to CollectionService:GetInstanceAddedSignal('canbedestroyed') and GetInstanceRemovedSignal('canbedestroyed') when no longer needed
