Door Script Auto Welding

Help and Feedback Scripting Support
#1

I am making a remake of a different door script I made in the past that had all doors being controlled from one script.

Here is how it works:

The script also welds all of the parts in DependentParts to MovablePart using a WeldingConstraint. There is only one issue with this: only one of the welding constraints is active at a time.

Here is my script:

function HoldingCard(plr, accessLevel)
	if ((plr.Character:FindFirstChildWhichIsA("Tool") and
		plr.Character:FindFirstChildWhichIsA("Tool"):FindFirstChild("AccessLevel"))
		and plr.Character:FindFirstChildWhichIsA("Tool"):FindFirstChild("AccessLevel").Value >= accessLevel) then
		return true
	end
	return false
end

function CardInBackpack(plr, accessLevel)
	for _,item in pairs(plr.Backpack:GetChildren()) do
		if item:FindFirstChild("AccessLevel") and item:FindFirstChild("AccessLevel").Value >= accessLevel then
			return true
		end
	end
	return false
end

for _,primaryDoor in pairs(workspace.Assets.Doors:GetChildren()) do 
	for __,door in pairs(primaryDoor.Doors:GetChildren()) do
		for ___,dependent in pairs(door.DependentParts:GetChildren()) do
			local weld = Instance.new("WeldConstraint", door.MovablePart)
			weld.Part0 = door.MovablePart
			weld.Part1 = dependent
		end
	end
	
	for ____,trigger in pairs(primaryDoor.Triggers:GetChildren()) do
		trigger.ProximityPrompt.Triggered:Connect(function(plr)
			if (HoldingCard(plr, primaryDoor.DoorAccessLevel.Value) or CardInBackpack(plr, primaryDoor.DoorAccessLevel.Value)) then
				trigger.ProximityPrompt.Enabled = false
				local val = (primaryDoor.IsOpen.Value and -.1) or .1
				primaryDoor.IsOpen.Value = not primaryDoor.IsOpen.Value
				for i=1,45 do
					wait(0.02)
					for _____,door in pairs(primaryDoor.Doors:GetChildren()) do
						door.MovablePart.CFrame = door.MovablePart.CFrame * CFrame.new(val,0,0)
					end
				end
				trigger.ProximityPrompt.Enabled = true
			end
		end)
	end
end

The solution I have tried was switching it to a normal weld but that didn’t work either.

I was wondering, how do I fix this?
