broken Armor esp???

hi,
so i was trying to code that armorbar in the forum. from V3enix
and it was going well but idk why but it wont activated...
i'll tell you what i did.
so first i get into my ESP.CPP and typed that code from him.
there where many errors i fixed it but not all of them ... Only that error --> g_bhealth or something like that, but i don't know how i can fix that
problem :/ so can someone help me with that pls? cause i don't know how i allready try it many times but it wont.

Or i dident activated cause i'm so stupid

so after i pasted that code into my esp.cpp
i get into menu.h and types into the visual tab:
CCheckBox OptionArmorBar;

i mean thats pretty logic...
after that i get into my menu.cpp and typed: OptionArmorBar.SetFileId("opt_ArmorBar");
OptionsGroup.PlaceLabledControl("ArmorBar", this, &OptionArmorBar);
where it have to be i think.
so i did only that but idk what iam doing wrong :/
can someone plss help me????
