Woops, then it would be the first value you specified in AddStaticPickup.
public OnPickedUp(pickupid, playerid)
{
	if( pickupid == 1 ) // The Pickup number here 
	{
	SendClientMessage(playerid, COLOR_YELLOW, "Esto es un Pickup ID 407" );
	return 1;
	}
    else if( pickupid == 2)   // The second pickup number here
	{
	SendClientMessage(playerid, COLOR_YELLOW, "Esto es un Pickup ID 406" );
        
 	return 1; // And you are lose in this 
                }
}
Something like this. I don't know what your Pickup IDs are so configure them yourself.
