first of all im new here and im really sorry if there's some mistakes when im making this question. So im trying to make a program to calculate using serial read, and im going to input a lot of values.

These are the codes that im trying to upload, but it wont shows the input.

int PpmNeed;
int Ppmpertank;
int nyala;
int tangki;
int sensor;
int mlkeluar;
void setup() {
  Serial.begin(115200);
  Serial.setTimeout(10);
}

void loop() {
    Serial.println("Besar Tangki");
    while(Serial.available() == 0){}
    tangki = Serial.parseInt();
    
    Serial.println("Kadar Dari Sensor");
    while(Serial.available() == 0){}
    sensor = Serial.parseInt();
    
    Serial.println("Data Perlakuan");
    while(Serial.available() == 0){}
    perlakuan = Serial.parseInt();
   
    Serial.print("Besar Tangki : ");
    Serial.println(tangki);
    Serial.print("Kadar Dari Sensor : ");
    Serial.println(sensor);
    Serial.print("Data Perlakuan : ");
    Serial.println(perlakuan);
}
