        draw.DrawText( "FireRate: "..tostring(ActvWeap:Delay()), "Trebuchet24", ScrW()-40, ScrH()-175, Color(0,64,128,255), 2 )

        draw.DrawText( "Accuracy: "..tostring(ActvWeap:Cone()), "Trebuchet24", ScrW()-40, ScrH()-225, Color(0,64,128,255), 2 )    
        draw.DrawText( ActvWeap:GetPrintName(), "Trebuchet24", ScrW()-40, ScrH()-275, Color(255,64,64,255), 2 )    
        draw.DrawText( "Experience: " .. DrExp, "Trebuchet24", ScrW()-40, ScrH()-325, Color(255,64,64,255), 2 )    
            end
    end
hook.Add("HUDPaint", "myhud", myhud)

function hidehud(name)
    for k, v in pairs{"CHudHealth", "CHudBattery", "CHudAmmo", "CHudSecondaryAmmo"} do
        if name == v then return false end
    end
end
hook.Add("HUDShouldDraw", "hidehud", hidehud)

As you can see i want to display the properties of weapons on the hud my problem is they keep returning nil does anyone know the correct way to get those values?
