Remote Events not working properly?

I decided to try remote events with my spawning script. However, they are not working as I'm new to remote events. The event does fire, the server script isn't picking it up though.

Server Script (in ReplicatedStorage):

train = game.ReplicatedStorage.C70Freight
Camera = workspace.CurrentCamera
DriveFrame = GUI.Screen.DriveFrame
Spawning = GUI.Screen.Spawning

script.Parent.Parent.Events.C70Spawn.OnServerEvent:connect(function(player)
        GUI = player.PlayerGui.MainMenuGui
        DriveFrame.Visible = false
        Spawning.Visible = true
        Spawning.Text = "Spawning..."
        wait(0.01)
        local clone = train:Clone()
        clone.Parent = workspace
        clone:MakeJoints()
        wait(1)
        player.Character.HumanoidRootPart.CFrame = CFrame.new(610.265, 6.551, -3143.202)
        Spawning.Visible = false
        player.CameraMode = "Classic"
        Camera.CameraType = "Custom"
        Camera.FieldOfView = 80
        wait(1)
        GUI.Screen.IntroMusic:Stop()
end)

LocalScript (in Gui)

Frame = script.Parent.Parent
C70 = Frame:WaitForChild("Set1")
Player = game.Players.LocalPlayer

function C70Clicked()
    if workspace:IsRegion3Empty(Region3.new(Vector3.new(467.505, 6.548, -3076.283), Vector3.new(1152.544, 6.559, -3298.865))) then
    game.ReplicatedStorage.Events.C70Spawn:FireServer()
    else
script.Parent.Text = "Spawn Occupied! Please Wait."
wait(1)
script.Parent.Text = "4 Wagons"
    end
end

C70.MouseButton1Click:connect(C70Clicked)
