How do i make that GUI Visible? not sure what i did wrong

So i have this code right here, what it does is make the next parts appear in the obby. and i want it to be if the player doesnt have above 100, he will get a pop up UI. and i did that at the bottom, and for some reason it just doesnt turn visible (The UI) in game it says its visible but its not shown. i really need help here. this is a script btw not a local script.

local PP = script.Parent.ProximityPrompt
local PPS = game:GetService("ProximityPromptService")
local pad = game.Workspace.Cloud1.Obby1["Obby Start  - 100$"].Head
local OtherPPS = game.Workspace.Cloud1.Obby2["Lava Stripes - 500$"].Head.ProximityPrompt
PP.Triggered:Connect(function(player)
    local Teams = game:GetService("Teams")
    if player.Team == Teams.Red  then
        local OtherPads = {game.Workspace.Cloud1.Obby2["Lava Stripes - 500$"].Head}
        local points1 = player:FindFirstChild("leaderstats") 
        if points1.points.Value >= 100 then
            points1.points.Value = points1.points.Value - 100
            pad:Destroy()

            local nextbutton = game.Workspace.Cloud1.Obby2["Lava Stripes - 500$"].Head
            local Checkpoint = game.Workspace.CheckPoints["1"]
            local Checkpointd = game.Workspace.CheckPoints["1"].Decal

            Checkpoint.Transparency = 0
            Checkpointd.Transparency = 0

            local parts = game.Workspace.Obby1.Jumps:Getchildren()


            for i, v in pairs(parts) do
                v.Transparency = 0
                v.CanCollide = true
                v.CanTouch = true
            end

            OtherPPS.Enabled = true
            for i, v in pairs(OtherPads) do
                v.Transparency = 0
                v.CanCollide = true
                v.CanTouch = true
            end

            nextbutton.Transparency = 0
        else
            local NotE = game.StarterGui.ScreenGui.Frame1
            NotE.Visible = true
        end
    end


end)
