Nextion display calling page and updating text- Very beginner Question

i am very new to display and programming. I was trying to update a text field on my 2nd page(i renamed it as weather). From the main page, i can able to navigate to 2nd page by clicking button(page navigation is from editor and i am not using Nextion library)

here is my code,

void show_weatherpage(){
    Temperature = dht.readTemperature(); // Gets the values of the temperature
    Humidity = dht.readHumidity(); // Gets the values of the humidity 
    Serial.println((int)Temperature);
    Serial.println((int)Humidity);
    mySerial.print(("weather.wetn0.val=" ));
    mySerial.print(((int)Temperature));
    //mySerial.print("");
    mySerial.print(("weather.wetn1.val=" ));
    mySerial.print(((int)Humidity));
    //mySerial.print("");
    mySerial.write(0xff);
    mySerial.write(0xff);
    mySerial.write(0xff);
  }

if i comment any of ""mySerial.print("weather.wetn** ( meaning updating one field ), display is updating value

If i enable both "mySerial.print(“weather.wetn”, both fields is going blank

Anyone please help me to achieve this

Thanks & Regards,
Ben

update :

after adding like below, both fields got updated

void show_weatherpage(){

    Serial.println((int)Temperature);
    Serial.println((int)Humidity);
    mySerial.print("weather.wetn0.val=" );
    mySerial.print((int)Temperature);
    mySerial.write(0xff);
    mySerial.write(0xff);
    mySerial.write(0xff);
    mySerial.print(("weather.wetn1.val=" ));
    mySerial.print(((int)Humidity));
    mySerial.write(0xff);
    mySerial.write(0xff);
    mySerial.write(0xff);
  }
