how to rotate a wall based of the attachment it's closest to?

so i have a bit of trouble and its with getting my wall to flip the right way heres the code

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local ToolEquiped = false
local Tool = script.Parent
Tool.Equipped:Connect(function()
	ToolEquiped = true
	Main()
end)

function Main()
	while ToolEquiped == true do
		wait(0.1)
		local WallPos
		local MouseTarget = mouse.Target
		local target
		if MouseTarget then 
			target = MouseTarget.name
		end
		if target == "foundation" then
			local ClosestDistance = math.huge
			local ClosestAttachment
			for _,attachment in pairs(mouse.Target:GetChildren()) do
				if attachment.Name == "floorAttachments" then
					local mousePos = mouse.Hit.p
					local worldPos = attachment.WorldPosition
					local distance = (mousePos - worldPos).Magnitude
					if distance < ClosestDistance then
						ClosestDistance = distance
						ClosestAttachment = attachment
					end
				end
			end
			local floor = mouse.Target
			local wall = game.Workspace.wall
			wall.Transparency = 0.75
			local wallCframe = floor.CFrame *CFrame.new(ClosestAttachment.Position)
			wallCframe = wallCframe *CFrame.new(wall.FloorAttachment.Position)
			wallCframe = wallCframe *CFrame.Angles(0, math.rad(ClosestAttachment.Orientation.Y), 0)
			wall.CFrame = wallCframe
			WallPos = wall.Position
		else
			local wall = game.Workspace.wall
			wall.Transparency = 1
		end
		Tool.Unequipped:Connect(function()
			ToolEquiped = false
			local wall = game.Workspace.wall
			wall.Transparency = 1
		end)
	end
end

ima using attachments and i belive the main peice of code to get it to rotate is *wallCframe = wallCframe CFrame.Angles(0, math.rad(ClosestAttachment.Orientation.Y), 0) but it dosent rotate at all any solutions? my discord is localLuser#4076
