local pos = {x = 1561, y = 1568, z = 7}
local pos1 = {x = 1562, y = 1568, z = 7}
local pos2 = {x = 1561, y = 1568, z = 7}
local pos3 = {x = 1562, y = 1568, z = 7, stackpos = 1}
local pos4 = {x = 1561, y = 1568, z = 7, stackpos = 1}

if item.itemid == 1440 then 
        doCleanTile(pos3,false)
        doCleanTile(pos4,false)
	doCreatureSay(cid, "Screech ~Ambiant Sound Of Rats Fighting Behind Wall~", TALKTYPE_ORANGE_1, false, cid, pos)
	doPlayerSendTextMessage(cid,22,"The platform you are standing on shakes for a second.")
