Game crashes with engine error?

[Leafdroid]

Any idea why this code causes the game to crash? It worked before I added the vehicles but I dont see anything wrong with them and the error I am getting is !weapons.Register. This code is located in an autorun file.

if SERVER then

vehicles = {
"sim_fphys_bak_gcpd_nova",
"drb_bf2_humvii",
"drb_bf2_buggi"
}
vehiclespawns = {
Vector(150, 150, 128),
Vector(-150, 150, 128),
Vector(150, -150, 128),
Vector(-150, -150, 128)
}

weapons = {
"weapon_357",
"weapon_smg1",
"weapon_ar2"
}
weaponspawns = {
Vector(15, 15, 128),
Vector(-15, 15, 128),
Vector(15, -15, 128),
Vector(-15, -15, 128)
}

concommand.Add( "fieldserver", function( ply, cmd, args )

for i=1,4 do 
local vehicle = ents.Create( table.Random(vehicles) )
vehicle:SetPos( table.Random(vehiclespawns) )
vehicle:Spawn()

local weapon = ents.Create( table.Random(weapons) )
weapon:SetPos( table.Random(weaponspawns) )
weapon:Spawn()
end

end)
end

[B]EDIT: Recoded it and somehow got it to work, although its telling me (Attempted to create unknown entity type *vehicle class here*!) even tho I can find them in my spawnlist.[/B]

That error means that the function weapons.Register doesn't exist in Lua when the SWEPs are about to load.

Usually caused by Lua error from editing game files ( you should never do this ) or addons that override said files ( you should never do that either )

[MeepDarknessM]

it's because he's making a global weapons table in that code

Stop creating global variables in first place
Your vehicles might not been working since most vehicles spawns prop_vehixle_jeep and then apply it script, those names are intended to name the vehicle in list.Add iirc

Don't use table.Random also.
Use tabname[math.random(#tabname)]
