i try make it wall buyable but it doesnt work at all
and i trying write the "ak47_zm" in zombie_mapname.gsc and _zombiemode_weapons.gsc but it again dont add ak47 in box

I think you have to add a couple of lines in _zombiemode_weapons.gsc and mapname.gsc and mapname.csv too. I don't exactly remember since it's been a while that I quit cod modding but you just literally look for similar lines(weapon lines) in the code and copy paste the same thing and you simply change the weapon name. As far as I can remember, the ak47 is a broken weapon in black ops 1, so you would have to find and download a ported weapon, and CFG Factory should be a good start. They also include the tutorial on how to install the content as well.
