I Need Help With This Code!

[Destined09]

This is my edited version of coolex's plastic explosive but i cant get it to work again after the player detonates one can someone help me???

local PLANTING_DELAY = 3 --seconds
local EXPLOSION_DELAY = 500 --milliseconds
local MAX_HIT = 800
local MIN_HIT = 400

local PVP = true -- true for PVP, false for Non-PVP


local PLAYERS = {}

function isInArray(table, valor)
for i,j in pairs(table) do
if (j == valor) then
return i
end
end
return 0
end

function explosion(info)
area = {
{0,0,0,0,0},
{0,1,1,1,0},
{0,1,1,1,0},
{0,1,1,1,0},
{0,0,0,0,0},
}
hitpos = {x=info.pos.x, y=info.pos.y, z=info.pos.z, stackpos=253}
center = {}
center.y = math.floor(table.getn(area)/2)+1
for i in ipairs(area) do
center.x = math.floor(table.getn(area)/2)+1
for j, v in ipairs(area) do
if (v == 1) then
hitpos.x = info.pos.x + (j - center.x)
hitpos.y = info.pos.y + (i - center.y)
if (getTilePzInfo(hitpos) == 0) then
victim = getThingfromPos(hitpos)
effect = 4
if ((j == center.x) and (i == center.y)) then
doSendAnimatedText(hitpos,"KABOOOOOM",TEXTCOLOR_RE D)
hitpoints = MAX_HIT
effect = 5
else
hitpoints = math.random(MIN_HIT,MAX_HIT)
end
if (isPlayer(victim.uid) == 1) then
if (PVP == true) then
doPlayerSendTextMessage(victim.uid,20,"You have lost "..hitpoints.." hitpoints by "..getPlayerName(info.player).."'s plastic bomb")
else
hitpoints = 0
end
end
if (isCreature(victim.uid) == 1) then
doPlayerAddHealth(victim.uid,-hitpoints)
end
doSendMagicEffect(hitpos,effect)
end
end
end
end
end

function planting(info)

end
else
doPlayerSendCancel(cid,"You can not plant this bomb in a PZ!")
end
