RSSAntidote Bomb Issue (ZM 4.3)

[MYGO.pl]

Hi guys! I have almost finished my own zombie plague server but i still have a problem.
I would like to add a Antidote Bomb.
My original addon was Zombie Plague 4.3 fix5a .

This is the error:

PHP Code:

---

L 08/19/2021 - 14:45:54: Invalid CVAR pointer
L 08/19/2021 - 14:45:54: [AMXX] Displaying debug trace (plugin "zp_antidote.amxx", version "1.0")
L 08/19/2021 - 14:45:54: [AMXX] Run time error 10: native error (native "set_pcvar_num")
L 08/19/2021 - 14:45:54: [AMXX]    [0] zp_antidote.sma::fw_SetModel (line 114) 


---

The problem:
- It shows in Extra Items Menu, i buy it but when throw the grenade, it makes the same thing as flare grenade which is disabled. Also i have to say that i have Kill Bomb with supports the flare grenade. But it doesn't matter, why the antidote bomb is not an antidote and just a normal flare grenade?

Should i add some cvars maybe?
