[SCRIPT] Basic Light change wont work... please help

[reper1210]

I'm new to scripting and i've tired for three days to get a single light to go out when i walk into a specified area and i keep getting this error...


FATAL ERROR: Could not load script file 'custom_stories/confined/Maps/confined.hps'!
main (3, 1) : ERR : No matching signatures to 'AddEntityCollideCallback(string@&, string@&, string@&, string@&)'
main (19, 28) : ERR : Expected '('


And this is my script...


void OnStart()
{
AddEntityCollideCallback("Enter","Player","ScriptArea_1","TurnOffLight");
AddDebugMessage("OnStart!", false);
}

void OnEnter()
{
AddDebugMessage("OnEnter!", false);
}

void OnLeave()
{
AddDebugMessage("OnLeave!", false);
}

void TurnOffLight(string asParent, string asChild)
{
void SetLightVisible(string& Light, true);
}

In game i have an area called "ScriptArea_1" and a ceiling lamp called "Light". I've been following tutorials all over frictional games and i tried to do the tutorial "5.1 scripting a light" the exact way and that didn't work and could not find matching signatures either or w/e.
This script does function because the debugging works and before i tested auto changing maps and giving my a lantern to start with with also both worked.

I appreciate any help in advance if anyone is will to try and solve this.
