Hi, I'm new with arduino and coding , so I was trying to control a Dc motor'sspeed and direction with keypad on proteus!but when i run it , it's not warking , pins low and high change but dc motor direction is not changing!

is it something wrong with my wiring or coding! does any one know how can i fix it?

#include <Keypad.h>

//Pins of L298
int in1 = A0; //Declaring where our module is wired
int in2 = A1;
int ConA = 3;
int Mspeed = 150;


const byte ROWS = 4; //4 rows
const byte COLS = 4; //4 columns
char keys[ROWS][COLS] = {
  {'7', '8', '9', '/'},
  {'4', '5', '6', '*'},
  {'1', '2', '3', '-'},
  {'C', '0', '=', ' '}
};
byte rowPins[ROWS] = {11, 10, 9, 8};  //connect to the row pinouts of the keypad
byte colPins[COLS] = {7, 6, 5, 4};  //connect to the column pinouts of the keypad

Keypad key = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );


void setup() {
Serial.begin(9600);
pinMode(ConA, OUTPUT);  
pinMode(in1, OUTPUT); // declare as output for L298 Pin in1 
pinMode(in2, OUTPUT); // declare as output for L298 Pin in2 
analogWrite(ConA, Mspeed); 
digitalWrite(in1,HIGH);
digitalWrite(in2,LOW);
delay(200);
}


void TurnMotorA(){
analogWrite(ConA,Mspeed);
char keys = key.getKey();


if (keys != NO_KEY){
  if (keys == '2'){
    if(Mspeed <= 255){
      Mspeed  ;}}


  if (keys == '8'){
    if(Mspeed >= 5){
      Mspeed--;}}

  if (keys == '4'){
    digitalWrite(in1,HIGH);
    digitalWrite(in2,LOW);
  }

  if (keys == '6'){
    digitalWrite(in1,LOW);
    digitalWrite(in2,HIGH);
  }

  if (keys == '5'){
    digitalWrite(in1,HIGH);
    digitalWrite(in2,HIGH);
  }

Mspeed = analogRead(keys);
delay(50);
}

}

void loop() {
TurnMotorA();
}
