BTS7960B Motor Driver Not Working!

Hi, So I have the BTS7960B Motor Driver connected to the arduino and it is not working at all we have tried searching online for a code that might make it work but nothing. This is the code we are currently using.

// Arduino code for the H_BRIDGE

int LPWM = 9; // H-bridge leg 1 ->LPWM
int enL = 8; // H-bridge enable pin 1 -> L_EN

int RPWM = 6; // H-bridge leg 2 ->RPWM
int enR = 9; // H-bridge enable pin 2 -> R_EN

void setup()
{
Serial.begin (9600);
pinMode(LPWM, OUTPUT);
pinMode(RPWM, OUTPUT);
pinMode(enL, OUTPUT);
pinMode(enR, OUTPUT);

digitalWrite(enL, HIGH);
digitalWrite(enR, HIGH);
}

void loop()
{
analogWrite(RPWM,100); //pwm value
digitalWrite(LPWM, LOW);

}

We connected 9.6V to VCC and Ground. Please if anyone can help this is for a school project. All we want to see right now is that the motor driver isnt defective so any code that will make one of the motors move will be perfect.

You do realise that you've defined pin 9 twice? Since both LPWM and ENR are both on pin 9.

How did you connect the H-bridge chip? Please tell what is on each of the 7 pins.
