Local handle help? (new to jass)

[i_am_cuul]

So im trying to make a spell that uses kattana's local handle scripts, however i, 1, cant come across an original one directly from kattana and 2, whenever i try to copy others, i get compile errors (i have tried 2 different sources, and the first error on the list is in:

function H2I takes handle h returns integer
    return h
    return 0
endfunction

    return 0

Invalid type for specified operator)

I just need to learn how to use the system, and, does it require some other thing? (such as vjass or whatever, i just use the normal editor)

Heres the rest of the code; the bottom portion was specific to the spells in the spellpack i got this from

Please do not use LHV, it is very buggy and can cause handle stack corruption in your maps.
It also does not work natively with patch 1.24.

I would be much wiser to use hashtables, which where introduced in these recent patches.

If you are insisting you must use LHV's, replace it with this. It's just a hashtable wrapper anyways.
