Can somene help me with my block placer script thats not working right?

I want to make it so my tool can place blocks when its equipped and cant when its unequipped. But I want it to place a lot of blocks and not just one. Right now the problem is when I move the mouse it keep creating more can this get fixed and still work the way I want it to?

code...

	wait(2)
	local player = game.Players.LocalPlayer
	local mouse = player:GetMouse()
	local blankPart = game.Players.LocalPlayer.PlayerGui.BlockGui.Block.Part
	blankPart.Anchored=true
    blankPart.CanCollide=false
	blankPart.Transparency=0.75

	local connection
	
	
	
	connection = mouse.Move:Connect(function() --If the mouse moves
	        wait(0.1)
	        local part = blankPart:Clone() --Clone part
	        part.Parent=workspace  --Parent = workspace
	        mouse.TargetFilter=part --ignore the clone while getting mouse position
	        local moveConn  --Variable move connect
	        moveConn = mouse.Move:Connect(function() -- Mouse -- moves function
	            local p = mouse.Hit.p  -- Mouse click position
	            part.Position = Vector3.new(math.floor(p.X),math.ceil(p.Y),math.floor(p.Z)) --mouse position in whole numbers
	        end)
	        mouse.Button1Down:Wait() --Do not have to connect a click function :)
			
			
	        moveConn:Disconnect() --Stop moving the clone
	        part.CanCollide=true  --Can collide = true
	        part.Transparency=0  --Transperancy = 0
	end)
