[SOLVED] How do I solve this problem with TextBounds?

So, I'm making a custom chat, but instead of making it simple I want to have the player's name a different color/font to the rest of the message. This somehow works perfectly in studio but does not work properly in online mode as seen in this place. How do I fix this problem, here's my function which returns no errors, works perfectly in studio but not in online mode:

function addMessage(speaker,msg,chat,color)
	for i,v in pairs(chat:GetChildren()) do
		if v:IsA("Frame") and string.sub(v.Name,1,7) then
			v.ActualPosition.Value = v.ActualPosition.Value-32
			v:TweenPosition(UDim2.new(0,5,0,v.ActualPosition.Value),"Out","Sine",0.5,true)
			v.Name = "Message"..tostring(tonumber(string.sub(v.Name,8))+1)
			if v.Name == "Message6" then
				v:TweenPosition(UDim2.new(0,5,0,-62),"Out","Sine",0.5,true)
				game:GetService("Debris"):AddItem(v,0.5)
			end
		end
	end
	local ChatFrame = Instance.new("Frame",chat)
	ChatFrame.Name = "Message1"
	ChatFrame.BackgroundTransparency = 1
	ChatFrame.Position = UDim2.new(0,5,0,149)
	ChatFrame.Size = UDim2.new(0,0,0,32)
	local ActualPosition = Instance.new("IntValue",ChatFrame)
	ActualPosition.Name = "ActualPosition"
	ActualPosition.Value = 149
	local Name = Instance.new("TextLabel",ChatFrame)
	Name.Name = "Name"
	Name.BackgroundTransparency = 1
	Name.TextColor3 = color
	Name.TextStrokeTransparency = 0.5
	Name.Font = "SourceSans"
	Name.FontSize = "Size18"
	Name.Text = speaker
	Name.Size = UDim2.new(0,Name.TextBounds.X,0,Name.TextBounds.Y)
	Name.ZIndex = 2
	local Message = Instance.new("TextLabel",ChatFrame)
	Message.Name = "Message"
	Message.BackgroundTransparency = 1
	Message.TextColor3 = Color3.new(255,255,255)
	Message.Font = "SourceSansLight"
	Message.FontSize = "Size18"
	Message.TextXAlignment = "Left"
	Message.TextYAlignment = "Top"
	Message.TextWrapped = true
	Message.Text = msg
	Message.Size = UDim2.new(0,350,0,36)
	Message.Position = UDim2.new(0,Name.TextBounds.X+2,0,0)
	Message.ZIndex = 2
	local Shadow = Message:Clone()
	Shadow.Parent = Message
	Shadow.TextColor3 = Color3.new(0,0,0)
	Shadow.Position = UDim2.new(0,-1,0,1)
	Shadow.ZIndex = 1
end

If you really want to see the rest of the script go here, although I don't see any reason why the rest of it would affect it. THIS IS IN A SERVER SCRIPT!

What the guy that answered said!
