Im making a plugin, which allows the player to carry several weapons. So I have tried a lot of ways, but this is most simple. Here is my code:

public Action:EventItemPickup2(client, entity) 
{ 
	char buffer[64]; 
	GetEntityClassname(entity,buffer,sizeof(buffer));
	if(weaponInHand[client]==0)
	{
		weaponInHand[client]=1;
	}
	for(int i=0;i<weaponCount;i++) 
	{ 
		if((!weapPick[i]) && (entList[i]==entity)) 
		{ 
			weapPick[i]=true; 
			new ammotype = GetEntProp(entity, Prop_Send, "m_iPrimaryAmmoType"); 
			SetEntProp(client, Prop_Send, "m_iAmmo", weaponReserve(buffer), _, ammotype); 
			SetEntProp(entity, Prop_Send, "m_iClip1", weaponClip(buffer));
			clientsWeapon[client][weaponInHand[client]]=entity;
			return Plugin_Continue; 
		}
		else if((weapPick[i]) && (clientsWeapon[client][i]==entity))
		{
			new ammotype = GetEntProp(entity, Prop_Send, "m_iPrimaryAmmoType"); 
			SetEntProp(client, Prop_Send, "m_iAmmo", weaponAmmo[client][i], _, ammotype);
		}			
	} 
	return Plugin_Continue;
}

public Action:OnEntityTouch(entity, other)
{  
    if((IsValidPlayer(other)) && (isWeapon(entity)))
    {
		float pos[3]={0.0,0.0,-100.0};
		int j=1;
		while(clientsWeapon[other][j]!=0)
		{
			j++;
		}
        clientsWeapon[other][j]=entity;
		PrintToChat(other,"Weapon %i was added to your backpack",entity);
		if(weaponInHand[other]==0)
		{
			weaponInHand[other]=1;
		}
		else
		{
			TeleportEntity(entity, pos, NULL_VECTOR, NULL_VECTOR);
		}
    }
}

void scrollBackpack(int client)
{
	char buffer[40];
	float pos[3]={0.0,0.0,-100.0};
	PrintToChat(client,"Номер оружия в руках %i", weaponInHand[client]);
	int nextWeap=weaponInHand[client]+1;	
	if((weaponInHand[client]==35) || (clientsWeapon[client][weaponInHand[client]]==0))
		nextWeap=1;
	PrintToChat(client,"Номер следующего оружия в руках %i", nextWeap);
	
	if(clientsWeapon[client][weaponInHand[client]]!=0)
	{
	new ammotype = GetEntProp(clientsWeapon[client][weaponInHand[client]], Prop_Send, "m_iPrimaryAmmoType"); 
	weaponAmmo[client][weaponInHand[client]]=GetEntProp(client, Prop_Send, "m_iAmmo", _, ammotype);
	CS_DropWeapon(client, clientsWeapon[client][weaponInHand[client]], true, true);
	PrintToChat(client,"Оружие %i сброшено", clientsWeapon[client][weaponInHand[client]]);
	TeleportEntity(clientsWeapon[client][weaponInHand[client]], pos, NULL_VECTOR, NULL_VECTOR);
	SetEntPropEnt(clientsWeapon[client][nextWeap], Prop_Send, "m_hOwnerEntity", client);
	2477: EquipPlayerWeapon(client, clientsWeapon[client][nextWeap]);
	ammotype = GetEntProp(weaponAmmo[client][nextWeap], Prop_Send, "m_iPrimaryAmmoType");
	SetEntProp(client, Prop_Send, "m_iAmmo", weaponAmmo[client][weaponInHand[client]], _, ammotype);
	}
	weaponInHand[client]=nextWeap;
}

It works very strangely. I have changed it a lot of times, but it gives in logs the same exeption:
L 05/19/2017 - 1729: [SM] Exception reported: Property "m_iPrimaryAmmoType" not found (entity 0/worldspawn)
L 05/19/2017 - 1729: [SM] Blaming: deathmatch-ryukzak_cherez_sbros.smx
L 05/19/2017 - 1729: [SM] Call stack trace:
L 05/19/2017 - 1729: [SM] [0] GetEntProp
L 05/19/2017 - 1729: [SM] [1] Line 2477

It put weapon in a "backpack" correctly, but didn't scroll it. I hope for your help, mb I missed something.

As the error message says, you're calling GetEntProp with entity ID 0. That's not a weapon.

Yes, I know. But how can there be taken zero, cause i checked it:
if(clientsWeapon[client][weaponInHand[client]]!=0)

[Totenfluch]

you should always store the reference to an entity, not the entity itself

You have a ton of different calls to GetEntProp. The one immediately after that particular if statement is certainly not the one causing the error. You didn't provide enough information.
