XP System working out how much XP they just gained help

[jacobcooper18]

   
local client = LocalPlayer()
xptable = {}
   if xptable == nil then
      table.insert( xptable, tonumber(client:GetNWInt( "XPBar" )) 
   elseif tonumber(client:GetNWInt( "XPBar" )) != tonumber(xptable) then
      client:PrintMessage( HUD_PRINTTALK, "+"..math.Clamp( client:GetNWInt( "XPBar" ), 0, xptable ) )
	  table.Empty( xptable )
   end   

Well I have an Leveling system but, I wan't to display a +(how much xp they just gained) system to my leveling system. Like when a player has more XP then, the inserted table then display how much xp they just gained. Aka, little johnny got +150, and then in chat he saw: +150. Little johnny was super excited! Is this how you work out the difference between xptable and the client:GetNWInt()? with math.Clamp. And using insert tables? Or is that wrong, because I want this on each individual player.
Thanks please help jacob :D

Why are you doing

tonumber(xptable)

When the table isn't a number?
Your code always confuses me a bit until I read it for a few minutes :p

I feel like you've totally over complicated what you want to accomplish

If I were doing a system like the one I think you're trying to do, I'd probably do something like this instead:

xptable = {}

local client = LocalPlayer()

local XPBarNumber = tonumber(client:GetNWInt( "XPBar" ))

xptable[ client ] = xptable[ client ] or XPBarNumber -- This sets it to XPBarNumber if the table key for the player was nil before

if xptable[ client ] ~= XPBarNumber then

	local diff = XPBarNumber - xptable[ client ]
	
	client:PrintMessage( HUD_PRINTTALK, "+"..diff )
	
	xptable[ client ] or XPBarNumber
	
end

God knows if it makes sense to anyone except me, but it looks better in my head
