Replacement Pack

[CalamityUSSOCOM 11]

Hey guys I have been trying to figure out how to replace the ACE M4 GL CCO SD Weapon with another weapon.

class ACE_M4A1_AIM_GL_SD: ACE_M4A1_AIM_GL_SD

{

displayName = "(Classified)";

model = "(Classified).p3d";

picture = "(Classified).paa";

handAnim[] = {"OFP2_ManSkeleton","Classifiedanim.rtm"};

discreteDistance[] = {50,100,200,300,400,500,600};

discreteDistanceInitIndex = 3;

weaponInfoType = "RscWeaponZeroing";

And well everytime I try to pack it it gives me an error and the error says that I used an Undefined Base Class.

Does anybody know how to fix it?
