RemoteEvent is not a valid member of Folder "ReplicatedStorage.StandFolder.RemoteEvents?"

I'm making a Jojo game and I'm trying to figure out the summon/punching part. This comes up in the output when I try to summon my character Here's the script

local TweenService = game:GetService("TweenService") local RunService = game:GetService("RunService")

local mainFolder = game.ReplicatedStorage.StandFolder
local Summon = mainFolder.RemoteEvents.Summon
local Punching = mainFolder.RemoteEvents.Punching
local Lean = mainFolder.RemoteEvents.Lean

Summon.OnServerEvent:Connect(function(player, isActive)
    local char = player.Character
    local hrp = char.HumanoidRootPart

    if isActive == true then
        local Stand = mainFolder.Models.Stand:Clone()
        local mainPart = Stand.PrimaryPart

        Stand.Parent = char
        mainPart.CFrame = hrp.CFrame

        local weld = Instance.new("ManualWeld")
        weld.Name = "Weld"
        weld.Part0 = mainPart
        weld.Part1 = hrp
        weld.C0 = mainPart.CFrame:ToObjectSpace(hrp.CFrame)
        weld.Parent = weld.Part0

        for i, bodyPart in pairs(Stand:GetChildren()) do
            if bodyPart:IsA("BasePart") and bodyPart ~= mainPart then
                local info = TweenInfo.new(0.45)
                local goal = {Transparency = 0}

                local tween = TweenService:Create(bodyPart, info, goal)
                tween:Play()
            end
        end

        local info = TweenInfo.new(0.5)
        local goal = {}
        goal.C0 = weld.Part0.CFrame:ToObjectSpace(weld.Part1.CFrame)
        goal.C1 = weld.Part0.CFrame:ToObjectSpace(weld.Part1.CFrame * CFrame.new(-3, 1.5, 3))

        local tween = TweenService:Create(weld, info, goal)
        tween:Play()

        local AnimControl = Stand.AnimationController
        local Idle = AnimControl:LoadAnimation(script.Animations.Idle)
        Idle:Play()
    else
        local Stand = char:FindFirstChild("Stand")
        local mainPart = Stand.PrimaryPart

        if Stand then
            if Stand.PrimaryPart:FindFirstChild("Weld") then
