[SCRIPT] Error with scripts

[MaksoPL]

Hi. I've got an error with a script:
main (10,1) Unexpected token '{'
main (15,16) Expected identifier
main (16,1) Unexpected token '}'

My .hps file:

void OnStart()
{
SetSanityDrainDisabled(true);

GiveItemFromFile("lantern", "lantern.ent");

for(int i=0;i< 25;i++) GiveItemFromFile("tinderbox_"+i, "tinderbox.ent");
}

{
AddEntityCollideCallback("Player", "12_girl_scream", "GirlScream", true, 1);
AddEntityCollideCallback("Player", "message1", "Message1", true, 1);
AddEntityCollideCallback("Player", "message2", "Message2", true, 1);
}
PlaySoundAtArea("12_girl_scream", "12_girl_scream.snt", "GirlScream01", 0, false);
}
void Message1(string &in asChild, string &in asParent, int alState)
{
SetMessage("Messages", "Wiadomosc1", 10);
}

void Message2(string &in asChild, string &in asParent, int alState)
{
SetMessage("Messages", "Wiadomosc2", 10);
}

void OnEnter()
{
PlayMusic("07_amb", true, 1.0f, 4.0f, 1, true);

}
What i've must do?
