[SCRIPT] Script Error

[MaksoPL]

Error is:
main (8,1) : ERR :Expected ',' or ';'

That's my script:
void OnStart()
{
AddUseItemCallback("","ham1","board1","ActivateBrokenBoards",false);
AddEntityCollideCallback("Player","grunt_script1","Hallucination",true,1);
}

void ActivateBrokenBoards(string &in asItem, string &in asEntity)
void Hallucination(string &in asParent, string &in asChild, int alState)
{
SetEntityActive("board1",false);
SetEntityActive("boardb1",true);
SetEntityActive("haluc1",true);
ShowEnemyPlayerPosition("haluc1");
RemoveItem("Ham1");
GiveSanityBoostSmall();
CreateParticleSystemAtEntity("","ps_cog_stone.ps","BoardParticles", false);
CreateParticleSystemAtEntity("","ps_break_mansionbase_wall.ps","BoardParticles",false);
PlaySoundAtEntity("","player_crouch","Player",0.0f,false);
PlaySoundAtEntity("","break_wood.snt","Player",0.0f,true);
}
