Help with GUIS? [UNANSWERED]

So I am making a Chat GUI but with help from a website I have followed the instructions and made this.

Script in ServerScriptService:

function UpdateOldLabels(Parent) for i,v in pairs(Parent:GetChildren()) do if v.Name:sub(1,4):lower() == "line" then local LineNumber = v.Name:sub(5) if LineNumber == "12" then v:Destroy() else v.Name = "line"..tostring(tonumber(LineNumber) + 1) v.Position = v.Position - UDim2.new(0,0,0,15) end end end end

game:GetService("Players").PlayerAdded:connect(function(player) player.Chatted:connect(function(msg) for _,v in ipairs(game:GetService("Players"):GetChildren()) do UpdateOldLabels(v:WaitForChild("PlayerGui").ScreenGui.Frame) newchatline = Instance.new("TextLabel",v:WaitForChild("PlayerGui").ScreenGui.Frame) newchatline.Text = player.Name.. ": " ..msg newchatline.Size = UDim2.new(1,0,0,15) newchatline.Position = UDim2.new(0,0,1,-15) newchatline.Font = "SourceSansBold" newchatline.TextColor3 = Color3.new(1,1,1) newchatline.TextStrokeTransparency = 0 newchatline.BackgroundTransparency = 1 newchatline.BorderSizePixel = 0 newchatline.FontSize = "Size14" newchatline.TextXAlignment = "Left" newchatline.TextYAlignment = "Top" newchatline.ClipsDescendants = true newchatline.Name = "line1" end UpdateOldLabels(game:GetService("StarterGui").ScreenGui.Frame) newchatline:Clone().Parent = game:GetService("StarterGui").ScreenGui.Frame end) end)

So here it all works and all but I cant seem to find out how to make the font size of the text to be the same as the original ROBLOX chat gui So if you know how I could do that it would help a lot thanks! :D Also do you know how to get the script to show up right because it never does -_-
