can some check my lua script over

[towaly]

This is my first lua script its simple and I'm not done with it yet and I was wondering if some pne could check it over and give me some feed back or corrections on it.( also 99909 is the entry id of my lich ling)

Function The_Lich_King_OnEnterCombat(pUnit, Event)
pUnit:SendChatMessage(14, 7, "Who dares oppose The Lich King!")
end

Function The_Lich_King_MirrorImage(pUnit, Event)
pUnit:FullCastSpell(55342, pUnit: GetRandomPlayer, (0))
PUnit:RegisterEvent("The_Lich_King_MirrorImage", 10000, 0)
pUnit:SendChatMessage(14, 7, "The end is near!")
end

Function The_Lich_King_Death(pUnit, Event)
pUnit:SendChatMessage(14, 0, "Someone must sit upon the throne.")
end

RegisterUnitEvent(99909, 1, "The_Lich_King_OnEnterCombat")
RegisterUnitEvent(99909, 2, "The_Lich_King_MirrorImage")
RegisterUnitEvent(99909, 3, "The_Lich_King_Death")

Also change the spell 55342 to another one, the spell is selfcast and in your script you are trying to cast on a random player. You need to check other Lua Scripts too, to understand the syntax better.
