Working on Portals, related questions

[Taugeshtu]

Hi.
Because ChestShop can't be done right now, I switched my attention at portals plugin.
Idea is: you create a warp (exit) point, then you select an entrance volume using wooden sword, add some chat command magic and TADA - you got one-way portal, which could be used for both in-world and interworld travels.

If you need two-way portal, you simply create warp points inside two entrances and link them cross-like.

Right now I faced a problem: I can't get player's name inside OnBlockPlace() hook

Simple code like this:

Code:

function OnBlockPlace(PacketData, Player)    -- RIGHTCLICK!
    LOG("PLAYER NAME IS: "..Player:GetName())
    return false
end

Gave me an error like that:

Code:

-- Plugins/Portal/portal_main.lua:73: attempt to index local 'Player' (a number value)

Whose fault it that and how to fix it?
