i need help on how to make a proximity prompt load multiple guis by chance anyone can help?

If you would like to make it so when a brick is touched a gui appears, i reccommend reading this forum post from another user. You can then just make the brick transparent and CanCollide ticked off.

With the implementing the music part, its simple, im going to use the script I previously linked, but just implementing the music. You are going to want to add you music into the lighting tab.

    local Workspace = game.Workspace

    local Tpart = Workspace:WaitForChild("Part23") -- Defines a way to a part. Change Part23 to name of the Part.

    local Players = game:GetService("Players")

    local Music = game.Lighting.Test1 -- Make Test1 the name of your music.

    -- Code starts here

    local deb = 0

    -- Makes the frame visible

    Tpart.Touched:Connect(function(hit)

    if deb == 0 then

    deb = 1

    local char = hit.Parent

    if char then

    local hum = char:WaitForChild("Humanoid")

    if hum ~= nil then

    print("Opening the Gui")

    local Player = Players:GetPlayerFromCharacter(char)

    local PlayerGui = Player.PlayerGui

    local GuiToBeOpened = PlayerGui:WaitForChild("Test1") -- Change Test1 to name of the Screengui.

    Music:Play()
    GuiToBeOpened.Frame.Visible = true

    end

    end

    end

    end)

-- ?? Disappears the frame

    Tpart.TouchEnded:Connect(function(hit)

    if deb == 1 then

    deb = 0

    local char = hit.Parent

    if char then

    local hum = char:WaitForChild("Humanoid")

    if hum ~= nil then

    print("Opening the Gui")

    local Player = Players:GetPlayerFromCharacter(char)

    local PlayerGui = Player.PlayerGui

    local GuiToBeOpened = PlayerGui:WaitForChild("Test1") -- Change Test1 to name of the Screengui.

    Music:Stop()
    GuiToBeOpened.Frame.Visible = false

    end

    end

    end

    end)
