Placing Script Not Placing Properly?

Before We begin here are some things you should know the Heirarchy

Problem: The following script does everything it is saposed to do, but when the part if following the mouse, and when I finally place it, it does not place right It looks like this , although i want to be placed like this , Also if i leave the mouse still while I'm in placing mode, the item will get closer and closer

Script

local cam = game.Workspace.CurrentCamera
local Item = game.ReplicatedStorage.Building.Walls.WoodenWall
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local enabled = script.Parent.Enabled
local amount = script.Parent.Amount
local Placing = false


script.Parent.MouseButton1Down:connect(function()

if enabled.Value == true then
    enabled.Value = false
elseif enabled.Value == false then  
    enabled.Value = true
    end
if Placing == true then
    local Item2 = cam:WaitForChild('WoodenWall')
    local Torso = game.Workspace:WaitForChild(player.Name).Torso
    local mag = (Item2.Position - Torso.Position).magnitude
    print(mag)
    if mag <= 40 then
    Item2:WaitForChild('bob'):remove()
    Item2.Parent = game.Workspace
    Item2.CFrame = mouse.Hit + Vector3.new(0, 50, 0)
    Item2.CanCollide = true
    Placing = false
    enabled.Value = false
    amount.Value = amount.Value - 1
end
end
end)

script.Parent.MouseButton2Down:connect(function()
    if enabled.Value == true and amount.Value >= 1 then

        local Item2 = Item:Clone()
        Item2.Parent = cam
        local selectionBox = Instance.new("SelectionBox",Item2) --We set its parent, but not where it's going to overlay
        selectionBox.Adornee = Item2 
        selectionBox.Name = 'bob'
        selectionBox.Color = BrickColor.new("Lime green")
        Placing = true





        repeat
            wait(.1)
        Item2.CFrame = mouse.Hit
        until enabled.Value == false or amount.Value < 1        
    end

end)
