can i put an array of structs inside an array of structs?

Question

im trying to make a project where i can access multiple companies, and inside of each company there can be multiple coments and ratings, and this is what i came up with:

#define COMPANY_INITIAL_SIZE 20
#define SEARCHES_INITIAL_SIZE 20

#define TEXT_MAX_SIZE 200
#define NAME_MAX_SIZE 50
#define EMAIL_MAX_SIZE 50
#define TITLE_MAX_SIZE 50
#define ADDRESS_MAX_SIZE 70
#define LOCATION_MAX_SIZE 70
#define CATEGORY_MAX_SIZE 30

#define NIF_MIN_SIZE 100000000
#define NIF_MAX_SIZE 999999999

    enum category {
        microCompany = 1, pmeCompany, macroCompany
    };

    enum state {
        inactive, active
    };

    enum searchCamp {
        nif, businessArea, nameLocation
    };
    
    enum comentState {
        hidden,visible
    };

    typedef struct {
        char title[TITLE_MAX_SIZE];
        char text[TEXT_MAX_SIZE];
        char userName[NAME_MAX_SIZE];
        char userEmail[EMAIL_MAX_SIZE];
        enum comentState states;
    } Coment;

    typedef struct {
        int nota;
        char userName[NAME_MAX_SIZE];
        char userEmail[EMAIL_MAX_SIZE];
    } Rating;

    typedef struct {
        int Nif;
        char name[NAME_MAX_SIZE];
        enum category categories;
        int businessAreaCode;
        enum state states;
        char address[ADDRESS_MAX_SIZE];
        char location[LOCATION_MAX_SIZE];
        int postalCode;
        int comentCounter,comentSize;
        Coment coments;
        int ratingCounter,ratingSize;
        Rating ratings;
    } Company;

    typedef struct {
        int counter, size;
        Company *companies;
    } Companies;

but after trying to insert coments in the companies it gives me this error: subscripted value is neither array nor pointer nor vector.

void insertComent(Companies *companies) {
    int company, nif;
    char title[TITLE_MAX_SIZE], text[TEXT_MAX_SIZE], name[NAME_MAX_SIZE], email[EMAIL_MAX_SIZE];

    nif = getInt(NIF_MIN_SIZE, NIF_MAX_SIZE, "\nNIF [9 digits]: ");

    company = verifyIfCompanyExists(*companies, nif);
    if (company != -1) {

        readString(title, TITLE_MAX_SIZE, "\nTitle: ");

        strcpy(companies->companies[company].coments[companies->companies[company].comentCounter].title, title); //<- this is the line that gives the error.

        readString(text, TEXT_MAX_SIZE, "\nTitle: ");
        strcpy(companies->companies->coments.text, text);
        readString(name, NAME_MAX_SIZE, "\nUserName: ");
        strcpy(companies->companies->coments.userName, name);
        readString(email, EMAIL_MAX_SIZE, "\nEmail: ");
        strcpy(companies->companies->coments.userEmail, email);


    }
}

i tried searching if what i was doing was possible but nothing that i got told me anything.
