ENT:Touch Help Needed!

[Inevitibility]

Alright, so earlier I posted a thread asking how to run a function when two props came into contact with each other. One of the answers was to make an entity and use the ENT:Touch function.

So I did. I know it is running because if I do this:

function ENT:Touch( sinep )
      if sinep:IsPlayer() then
            sinep:Kill()
      end
end

and it works. If I use a more complicated code, it doesn't do shit. I am trying to make it come in contact with a box, delete the box, and create a bath tub. This is my code:

function ENT:Touch( sinep )
      if ( sinep:GetModel() == "models/Items/item_item_crate.mdl" ) then
            local kcid = ents.Create( "prop_physics" )
                  kcid:SetModel( "models/props_interiors/BathTub01a.mdl" )
                  kcid:SetPos( Vector( 0, 0, 50 ) )
                  kcid:Spawn()
            sinep:Remove()
      end
end

If you can help educate me on how to make this work, then thank you VERY much!

Print the model of the touching entity to see if it is [b]exactly[/b] the same.

why is the position relative to the entity?
