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
