Scripts in ScreenGui not functioning on server?

Hi there, scripters! I ran into a problem when trying to make an interface located inside the player's ScreenGui. I am aware that the recent Roblox update forced FE on, but I can't seem to fix this. Any help is appreciated! Both of these scripts are inside of a textbox, inside of a ScreenGui:

Local script- indexes mouse and runs while loop:

wait(1)
mouse = game.Players.LocalPlayer:GetMouse()
speed = game.ReplicatedStorage.Speed:Clone()
speed.Parent = game.Players.LocalPlayer
health = game.ReplicatedStorage.Health:Clone()
health.Parent = game.Players.LocalPlayer

while wait(0.1) do
	for i,v in pairs(script.Parent:GetChildren()) do
		if v.Name == "SpeedButton" then
			v.Position = UDim2.new(0,speed.Value,0,v.Position.Y.Offset)
			script.Parent.Script.Adjust:FireServer(v,speed,health,mouse,"WalkSpeed","MaxHealth",0.17,1.05)
		end
		if v.Name == "HealthButton" then
			v.Position = UDim2.new(0,health.Value,0,v.Position.Y.Offset)
			script.Parent.Script.Adjust:FireServer(v,health,speed,mouse,"MaxHealth","WalkSpeed",1.05,0.17)
		end
		if v.Name == "Done" then
			v.MouseButton1Click:Connect(function()
				script.Parent.Visible = false
				script.Parent.Sound1:Play()
			end)
		end
	end
end

Script- receives fire server and mouse coordinates

click = 0

script.Adjust.OnServerEvent:Connect(function(player,v,value1,value2,mouse,property1,property2,x1,x2)
	v.MouseButton1Down:Connect(function()
		click = 1
		repeat
			wait(0.01)
			if mouse.X > 5 and mouse.X < 190 then
				value1.Value = math.floor(mouse.X/15)*15 + 5
				value2.Value = 190 - (math.floor(mouse.X/15)*15 + 5)
			end
			mouse.Button1Up:Connect(function()
				click = 0
			end)
		until click == 0
		player.Character.Humanoid[property1] = value1.Value * x1 + 10
		player.Character.Humanoid[property2] = value2.Value * x2 + 10
		player.Character.Humanoid.Health = player.Character.Humanoid.MaxHealth
	end)
end)

I'd also like to mention that this works fine in Studio, but on a server it's broken. It doesn't show any error messages in the output... Thanks!
