c Questions regarding initialization of language structure

typedef struct PersonArray {    
    Person people[NUM_USER];
    int total_waiting_time;     
    int total_waiting_people;   
}PersonArray;

PersonArray *PeopleArray;

PeopleArray->total_waiting_time = 0;
PeopleArray->total_waiting_people = 0;

The structure PersonArray set as the global variable.

And to create a PeopleArray with a structure pointer and initialize the contents of it

PeopleArray->total_waitting_time = 0; PeopleArray->total_waiting_people = 0;

I did, but an error mark appears in the -> part, so ';' is required That's what it says.

Did I do the wrong way to initialize the variables in the structure?

How do I initialize the global variable structure?

And

#include <stdio.h>
#include <stdlib.h>=
#define SIZE_QUEUE 100  //the maximum size of the news_queue
#define CAPACITY 6      //the capacity of ZNN.com (per sec)
#define NUM_USER 20     //the number of users
#define NUM_LOOP 100    //the number of loops


//ContentFidelity is one of the types: video, image, text
typedef enum { Video, Image, Text } ContentFidelity;

typedef struct {
    unsigned int requestedBy;
    ContentFidelity fidelity;
} news; // When user 8 requests a video, it outputs the requested news content as (8, video)

typedef struct {
    news queue[SIZE_QUEUE];
    unsigned int front;
    unsigned int rear;
} Queue; // Queue for stacking news content requested by the user

Queue *news_queue;
Content Fidelity current Fidelity = Video; // First content is video

                                         /**/
typeef structure Person { // User structure (content count and latency information)
    int content_num; // Total number of requested content
    int receive_content; // Total number of received content
    int waiting_time; // total delay time
    int content_score; // Total score of received content
}Person;

typeef structure PersonArray { // Structure for user structure (array)
    Person people[NUM_USER];
    int total_waiting_time; // Total latency
    int total_waiting_people; // Number of users who have requested content so far (redundant)
}PersonArray;

PersonArray *PeopleArray;

PeopleArray->total_waiting_time = 0;
PeopleArray->total_waiting_people = 0;
for (int i = 0; i < 20; i++) {
    PeoepleArray->people[i].content_num == 0;
    PeoepleArray->people[i].receive_content == 0;
    PeoepleArray->people[i].waiting_time == 0;
    PeoepleArray->people[i].content_score == 0;
}
