code not working

[Fexec]

As soon i try to use this code, the server wont start: :v:

function BlockCave()
if game.GetMap() == "rp_evocity_v2d" or game.GetMap() == "RP_EvoCity_v2d" then
local prop = ents.Create( "prop_physics" )
prop:SetPos( Vector(334.911041, 14592.786133, 256.710052) )
        prop:SetModel( "models/props_combine/combineinnerwall001c.mdl" )
prop:SetNWString("Owner", "World")
prop:Spawn()
prop:SetAngles(Angle(90, 0, 0))
prop:PhysicsInit(SOLID_VPHYSICS)  
prop:SetMoveType(MOVETYPE_NONE)
prop:SetSolid(SOLID_VPHYSICS)  
Msg("EvoCity CaveBlock Spawned\n")
local phys = prop:GetPhysicsObject()
if phys:IsValid() then
phys:Wake()
end
local prop2 = ents.Create( "prop_physics" )
prop2:SetPos( Vector(334.911041, 13074.386, 256.710052) )
        prop2:SetModel( "models/props_combine/combineinnerwall001c.mdl" )
prop2:SetNWString("Owner", "World")
prop2:Spawn()
prop2:SetAngles(Angle(90, 0, 0))
prop2:PhysicsInit(SOLID_VPHYSICS)  
prop2:SetMoveType(MOVETYPE_NONE)
prop2:SetSolid(SOLID_VPHYSICS)  
local phys2 = prop2:GetPhysicsObject()
if phys2:IsValid() then
phys2:Wake()
end
local prop3 = ents.Create( "prop_physics" )
prop3:SetPos( Vector(334.911041, 11631.906, 256.710052) )
        prop3:SetModel( "models/props_combine/combineinnerwall001c.mdl" )
prop3:SetNWString("Owner", "World")
prop3:Spawn()
prop3:SetAngles(Angle(90, 0, 0))
prop3:PhysicsInit(SOLID_VPHYSICS)  
prop3:SetMoveType(MOVETYPE_NONE)
prop3:SetSolid(SOLID_VPHYSICS)  
local phys3 = prop3:GetPhysicsObject()
if phys3:IsValid() then
phys3:Wake()
end

prop:SetNWBool("noclip", true)
prop:SetColor(0,0,0,0)
prop2:SetNWBool("noclip", true)
prop2:SetColor(0,0,0,0)
prop3:SetNWBool("noclip", true)
prop3:SetColor(0,0,0,0)
   end
end
hook.Add("InitPostEntity", "BlockCave", BlockCave)
hook.Call("InitPostEntity", "BlockCave", BlockCave)

Any help? And where do you need to put it exactly when using cider? the init or the cleanmap plugin?

Doesnt this stuff:

prop:PhysicsInit(SOLID_VPHYSICS)  
prop:SetMoveType(MOVETYPE_NONE)
prop:SetSolid(SOLID_VPHYSICS) 

Go before the prop:Spawn() of the entity?

And whats the point in the hook.Call?

Ok, so i did this, Now its an instant crash when people join. sum more help :v:
