spawning a prop

Hello

I want to a script that creates a prop using lua.
I already made something but it doesent work. In the console it gives the Null entity error.
Heres the Code:
[lua]
function spawnentitys()
if game:GetMap() == “gm_construct” then

local ent1 = ents.Create(“prop_static”)
ent1:SetAngles(Angle(-0.23, -179.95, 0.01))
ent1:SetPos(Vector(1098.35, 296.11, -127.20))
ent1:SetModel(“models/props_wasteland/controlroom_desk001b.mdl”)
ent1:Spawn()

end
end
hook.Add( “InitPostEntity”, “spawnentitys”, spawnentitys )
[/lua]

You can’t create prop_static’s, they’re embedded into the map on compile, use prop_physics and :SetMoveType(MOVETYPE_NONE) instead

ok thanks for the info!
