Script File crashing

void OnStart()
{
PlayMusic("amb_guardian.ogg", true, 1.0f, 0, 0, true);
}
{
AddUseItemCallback("", "bone_saw_2", "wooden_boards_block_1", "SawGruntAlert", true);
}

So, bold characters are completely needless. {'s are to open and close function blocks. Like in:
void TimerFunc2(string &in asTimer)
{
StopSound("23_saw2.snt", 0f);
}

See, void TimerFunc2(string &in asTimer) is the header, and { & } is to open and close the function block.
