Servo and DC motor with bts7960

Hello Everyone. I am having a problem running my servo with a DC motor. They work perfectly fine independently but the moment i combine them under one code, my DC motor only rotates in one direction.
Below you can see the code.

int RPWM=10;
int LPWM=11;
// timer 0
int L_EN=7;
int R_EN=8;
#include <Servo.h>

Servo myservo;

void setup() {

pinMode(RPWM,OUTPUT);
pinMode(LPWM,OUTPUT);
pinMode(L_EN,OUTPUT);
pinMode(R_EN,OUTPUT);

digitalWrite(RPWM,LOW);
digitalWrite(LPWM,LOW);
digitalWrite(L_EN,LOW);
digitalWrite(R_EN,LOW);

delay(1000);
Serial.begin(9600);
myservo.attach(9);
}

void loop() {

servo();
Serial.println(“EN High”);
digitalWrite(R_EN,HIGH);
digitalWrite(L_EN,HIGH);
Serial.println(“stop yet\n”);
delay(500);
Serial.println(“start CW\n”);
analogWrite(LPWM,50);

delay(5000);
analogWrite(LPWM,0);
Serial.println(“stop\n”);
delay(2000);
analogWrite(RPWM,50);
Serial.println("start CCW\n ");
delay(2000);
analogWrite(RPWM,0);
Serial.println("srop2\n ");
delay(2000);

}

void servo(){
myservo.write(90);
delay(1000);
myservo.write(0);
delay(1000);
}

int RPWM=10;

If you had read the Servo library reference you would have seen this:

use of the library disables analogWrite() (PWM) functionality on pins 9 and 10, whether or not there is a Servo on those pins.

The solution is to use a different PWM pin for RPWM.
