How would I space out my text labels in my custom made output?

So what I've been trying to do is whenever I say c/ it says running a script but it doesn't seem to space out the textlabels in the output. Can somebody please try to help me? I want it so that the text labels space out each time in my output. My own custom made one so that they don't overlap onto each other. I've tried adding the position but it doesn't seem to work.

game.Players.PlayerAdded:connect(function(player)
player.Chatted:connect(function(msg)
if msg:lower():sub(1,2) == "c/" then 
local code = loadstring(msg:sub(3)) code() 
local t = Instance.new("TextLabel",player:findFirstChild("PlayerGui").Output.Main)
t.BackgroundTransparency = 1
--UDim2.new(xscale,xoffset,yscale,yoffset)
t.Size=UDim2.new(0,200,0,50)
t.Text="Running a Script(Workspace.Script)"
t.TextWrapped=true
t.Position=UDim2.new(0,4,0,2)
t.Position=t.Position+UDim2.new(0,8,0,4)
t.TextColor3=Color3.new(0,170,255)
t.Visible = true
pcall(function() end)
pcall(function() end)
end
end)
end)
