How to make a button that prompts you every-time you step on it?

So, i created this script that when you press on these buttons they prompt you :)

Here's the script:

local MarketPlaceService = game:GetService("MarketplaceService")
    local Players = game:GetService("Players")

    local PromptSpeed = game.Workspace:WaitForChild("PromptSpeed")
    local PromptBox = game.Workspace:WaitForChild("PromptPart")
    local PromptPower = game.Workspace:WaitForChild("PromptJump")
    local PromptVip = game.Workspace:WaitForChild("PromptVIP")

    local function OnPromptPurchase(player, gamepassId)

        local HasPass = false

        local Humanoid = player.Parent:FindFirstChildOfClass("Humanoid")

        if (Humanoid) then
            player = Players.LocalPlayer

        HasPass = MarketPlaceService:UserOwnsGamePassAsync(player.UserId, gamepassId)  
        end

        if HasPass then
        print("Player has the gamepass!")
    end
        if not HasPass then
            PromptSpeed.Touched:Connect(function(player)
                MarketPlaceService:PromptGamePassPurchase(player, 8638546)
                end)

                    if not HasPass then
                        PromptBox.Touched:Connect(function(player)
                            MarketPlaceService:PromptGamePassPurchase(player, 8582273)
                    end)
                        if not HasPass then
                            PromptPower.Touched:Connect(function(player)
                                MarketPlaceService:PromptGamePassPurchase(player, 8796152)
                        end)
                            if not HasPass then
                                PromptVip.Touched:Connect(function(player)
                                    MarketPlaceService:PromptGamePassPurchase(player, 8757181)
                            end)
                        end
                        end
                   end
                        end
                        end
