How to place several scripts in the .hps file

[GoDiiXz]

now i know how it works, but my problem as said, i do not know where i put in example: void AddEntityCollideCallback(string& asParentName, string& asChildName, string& asFunction, bool abDeleteOnCollide, int alStates);

but i do not know where to put this script as i already have the door/key script there, to say it short: where do i put this scirpt: void AddEntityCollideCallback(string& asParentName, string& asChildName, string& asFunction, bool abDeleteOnCollide, int alStates);

please reply me a picture that shows where, in notepad++ offcourse ;D
