I don't know why I get so many errors on it.

If you have this

globals
    gamecache udg_AbilityCache
    trigger gg_trg_Stomp
endglobals

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

function I2G takes integer i returns group
    return i
    return null
endfunction

then it shouldn't be any errors. IE, pjass can't find errors if you add that code.
