Why wouldn't this script work?

[Battlefield3142]

(in OnStart)
AddEntityCollideCallback("Player", "popout1", "SetEntityActive", false, 0); (When player crosses a script box called popout1, an entity is set active.

then


void SetEntityActive(string& jesus, bool abActive);
{
if(HasItem("scarykey_1") == false) return;
SetEntityActive("jesus");
}

if a player has an item called scarykey_1, this wont happen and it will return to unactive
make entity (a rag doll called jesus) active.

for some reason I receive an error when launching the map.

not sure why.
