How to make more than 1 script?

[FrictionalWeekly]

I'm having trouble making my first custom story because I'm newby with scripts. I'm having trouble making 2 scripts in 1 map mainly and it's frustrating.

Here's what it is that I'm trying to do that's wrong somehow

_____________________________________________________________

void OnEnter()

{
PlayMusic("penumbra_music_E1_D1", true, 1, 0, 0, true);
}

void DoggyAttackPart(string &in asEntity, string &in type)
{
SetEntityActive("doggy", true);
StartPlayerLookAt("doggy", 15, 15, "");
AddTimer("monstertimer", 2, "monstertimer");
ShowEnemyPlayerPosition("doggy");
}

void monstertimer(string &in asTimer)
{
StopPlayerLookAt();
}


//////// Scare music in bloody room
void AddEntityCollideCallback("Player", "scare_script", "scare_script", false, 0);



void scare_script(string &in asParent, string &in asChild, int alState)
{
//music scripts here
// If enters and leave
if(alState == 1)
{
PlayMusic("Penumbra_BP_C1.ogg", false, 1.00, 0, 5, true);
}
if(alState == -1)
{

}

And this is the error that pops up when it tries to load the map.
