Hud Problem

[Coventry]

Hello guys, i have a problem with my hud, this is how it looks:
[IMG]http://gyazo.com/a2386943bb1ab5165be393d07eb6ea25.png?1365892805[/IMG]

The problem as you can see is that: my Level, Req Exp and Free Points values stay in 0, ( when i level up, all the values load correctly Like: Level: 22, Exp Rq: 259 Free Points: 8 )

This is my hud lua code:

[lua]
local function ExperienceHUD()
if !pl:Alive() then return end
if(pl:GetActiveWeapon() == "Camera") then return end
if(pl.RP_SQL == nil) then pl.RP_SQL = {}; end;

//Level
draw.RoundedBox( 0, 640, 9, 150, 18, Color( 125, 125, 125, 180 ) )
surface.SetDrawColor( Color( 65, 65, 65, 180 ) )
surface.DrawOutlinedRect( 640, 9, 150, 18 )

local strDisplay = "0" or pl.RP_SQL["StrengthLvl"];
local strXP = pl.RP_SQL["StrengthExp"] or "0";
draw.SimpleText( "Level: "..strDisplay , "TabLarge", 590 + 150 / 2 + surface.GetTextSize( "Level: ".. strXP ) / 2, 11, Color( 255, 255, 255, 255 ), 0, 0 )

//Exp
draw.RoundedBox( 0, 820, 9, 150, 18, Color( 125, 125, 125, 180 ) )
surface.SetDrawColor( Color( 65, 65, 65, 180 ) )
surface.DrawOutlinedRect( 820, 9, 150, 18 )

draw.SimpleText( "Req Exp: ".. tonumber(strDisplay) * 10 - tonumber(strXP) , "TabLarge", 750 + 150 / 2 + surface.GetTextSize( "Req Exp: ".. tonumber(strDisplay) * 10 - tonumber(strXP) ) / 2, 11, Color( 255, 255, 255, 255 ), 0, 0 )

//Points
draw.RoundedBox( 0, 1000, 9, 150, 18, Color( 125, 125, 125, 180 ) )
surface.SetDrawColor( Color( 65, 65, 65, 180 ) )
surface.DrawOutlinedRect( 1000, 9, 150, 18 )
local agilXP = pl.RP_SQL["AgilityExp"] or "0";

draw.SimpleText( "Free Points: "..agilXP , "TabLarge", 930 + 150 / 2 + surface.GetTextSize( "Free Points: "..agilXP) / 2 , 11, Color( 255, 255, 255, 255 ), 0, 0 )
end
hook.Add( "HUDPaint", "ExperienceHUD", ExperienceHUD )
[/lua]
