HUD problem

[breakyorself]

So when using this HUD(Kinda edited together two HUDs I found and changed them up a bit)

good_hud = { };
 
local function clr( color ) return color.r, color.g, color.b, color.a; end
 
function good_hud:PaintBar( x, y, w, h, colors, value )
 
    self:PaintPanel( x, y, w, h, colors );
 
    x = x + 1; y = y + 1;
    w = w - 2; h = h - 2;
 
    local width = w * math.Clamp( value, 0, 1 );
    local shade = 4;
 
    surface.SetDrawColor( clr( colors.shade ) );
    surface.DrawRect( x, y, width, shade );
 
    surface.SetDrawColor( clr( colors.fill ) );
    surface.DrawRect( x, y + shade, width, h - shade );
 
end
 
function good_hud:PaintPanel( x, y, w, h, colors )
 
    surface.SetDrawColor( clr( colors.border ) );
    surface.DrawOutlinedRect( x, y, w, h );
 
    x = x + 1; y = y + 1;
    w = w - 2; h = h - 2;
 
    surface.SetDrawColor( clr( colors.background ) );
    surface.DrawRect( x, y, w, h );
 
end
 
  
function good_hud:TextSize( text, font )
 
    surface.SetFont( font );
    return surface.GetTextSize( text );
 
end
 
function good_hud:PaintText( x, y, text, font, colors )
 
    surface.SetFont( font );
 
    surface.SetTextPos( x + 1, y + 1 );
    surface.SetTextColor( clr( colors.shadow ) );
    surface.DrawText( text );
 
    surface.SetTextPos( x, y );
    surface.SetTextColor( clr( colors.text ) );
    surface.DrawText( text );
 
end


local vars =
{
 
    font = "TargetID",
 
    padding = 10,
    margin = 2,
 
    text_spacing = 2,

    health_bar =

    LocalPlayer().DarkRPVars = LocalPlayer().DarkRPVars or {}
     
    local v1 = LocalPlayer().DarkRPVars.money
    if not v1 then v1 = "" end
     
    local v2 = LocalPlayer().DarkRPVars.salary
    if not v2 then v2 = "" end
 
    
    surface.SetDrawColor(255,255,255)
    surface.SetTexture(surface.GetTextureID("gui/silkicons/user"))

end
hook.Add( "HUDPaint", "PaintOurHud", HUDPaint );

I tried to add it to darkrp by replacing the client/hud.lua, and it works on singleplayer with DarkRP, but not on multiplayer. I get the error:
ags' changed to Evolve,SCars 2.0,garrysmod139,gm:DarkRP
Hook 'PaintOurHud' Failed: [@lua\includes\modules\draw.lua:103] bad argument #1 to 'DrawText' (string expected, got nil)
I have no idea how to fix this. Any help would be appreciated
