I cannot figure this out. Help?

So I just started scripting and I've been playing around with a couple effects and it was going pretty well. Then I started getting an error message saying "unexpected end of file" or something like that. I looked over this a thousand times but I just can't figure it out. Help?
void OnStart()
{
AddEntityCollideCallback("Player", "ScriptArea_1", "ScriptArea_1", true, 1);
AddEntityCollideCallback("Player", "nolantern", "nolantern", true, 1);
AddEntityCollideCallback("Player", "explode_door", explode_door", true, 1);
}

void ScriptArea_1(string &in asParent, string &in asChild, int alState)
{
if(alState == 1)
{
SetSwingDoorClosed("mansion_1", true, true);
}
}
void explode_door(string &in asParent, string &in asChild, int alState)
{
SetPropHealth("explode",0.0f);
}
void nolantern(string &in asParent, string &in asChild, int alState)
{
SetLanternDisabled(true);
}

The callback argument string for the third AddEntityCollideCallback was not properly opened.

Ahhhhh. Thank you very much. This is the first time I've ever coded and I literally learned how last night haha.
