GetPlayerWeaponSlot returns an index to an entity. That entity is the weapon held by said client in said slot. If the client, for some reason, does not have a weapon in that slot, GetPlayerWeaponSlot will return -1.

Look at SetGrenadeAmmo(client, ammo, index, slot) in your first post. Notice the use of IsValidEntity. You need to implement something similar in other parts of your code (e.g. the code we've been discussing).
