Help with Coding for multiple 4051

Hi everyone, i hope i can get somehelp on how getting this to work.

I have multiple Sensors (32 of these) i want to read their values. I am using a master multiplexer HC4051 connected to 4 slave multiplexers, this is my wirings :

i tested it using one single multiplexer and it workes as intended, but when adding the slave i cannot getting it to work, i am not sure how to code it.

When using this code :

// 74XX4051 ADDRESS PINS :
#define  M_S0 2
#define  M_S1 3
#define  M_S2 4

#define  S_S0 7
#define  S_S1 6
#define  S_S2 5

// 74XX4051 ANALOG PIN :
#define  Z 0


void setup(){

        // CONFIGURE ADDRESS PINS
        pinMode(M_S0, OUTPUT);
        pinMode(M_S1, OUTPUT);
        pinMode(M_S2, OUTPUT);

        pinMode(S_S0, OUTPUT);
        pinMode(S_S1, OUTPUT);
        pinMode(S_S2, OUTPUT);

        // CONFIGURE SERIAL
        Serial.begin(57600);
}

void loop () {

int value;

        // LOOP THROUGH ALL THE ADDRESSES OF THE MASTER 
        for ( byte count = 0; count < 4 ; count++ ) {

                // SET THE ADDRESS
                digitalWrite(M_S0, bitRead(count, 0) );   
                digitalWrite(M_S1, bitRead(count, 1) );
                digitalWrite(M_S2, bitRead(count, 2) );  // => 000 - Y1-Z
                
                // LOOP THROUGH ALL THE ADDRESSES OF THE SLAVES
                for ( byte count_1 = 0; count_1 < 32 ; count_1++ ) {

                    digitalWrite(S_S0, bitRead(count_1, 0) );   // => 000,000,000,000 => Z1, Z2, Z3, Z4
                    digitalWrite(S_S1, bitRead(count_1, 1) );
                    digitalWrite(S_S2, bitRead(count_1, 2) );

                    // READ THE ANALOG VALUE
                    value = (bitRead(count_1, 2),bitRead(count_1, 1),bitRead(count_1, 0));

                }

                // READ THE ANALOG FOR THE MASTER ADRESSE
                value = analogRead(Z);

                // SERIAL OUTPUT
                // print : ### value
                Serial.print(bitRead(count, 2));
                Serial.print(bitRead(count, 1));
                Serial.print(bitRead(count, 0));
                Serial.print(' ');
                Serial.println(value);

                delay(100);
        }

}

I’ am only getting random readings really (The reading LED for the moisture sensor does not switches on when the reading is done)
What i am doing wrong ? .
Any help will be appreciated.
