Also, why are you setting a PVar to 0 two times?

pawn Код:

SetPVarInt(targetid, "KnifeKilled", 0);
SetPVarInt(playerid, "KnifeKilled", 0);
SetPVarInt(playerid, "Knifing", 0);
SetPVarInt(targetid, "BeingKnifed", 0);
SetPVarInt(playerid, "BeingKnifed", 0);
SetPVarInt(targetid, "Knifing", 0);

It could be:

pawn Код:

SetPVarInt(targetid, "KnifeKilled", 0);
SetPVarInt(targetid, "BeingKnifed", 0);
SetPVarInt(targetid, "Knifing", 0);
