Can't find what's wrong

Here are my codes:

int BlueLED=9; //define blue red pin at 9
int BlueLEDontime=100;
int BlueLEDofftime=500;
int RedLED=7;
int RedLEDontime=100;
int RedLEDofftime=500;
int numBlueblink;
int numRedblink;
String Bluemesssage="The Blue is Blinking!";
String Redmessage="The Red is Blinking!";

void setup() {
Serial.begin(115200);
String wm1= "Welcome to ";
String wm2= "my program";
String wm3=wm1+wm2;
Serial.print(wm3);
Serial.println(" ");
pinMode(BlueLED,OUTPUT);
pinMode(RedLED,OUTPUT);

Serial.println("Please input the bluelink times?");
while (Serial.available()==0) { }
numBlueblink=Serial.parseInt();

Serial.println("Please input the redblink times?");
while (Serial.available()==0) { }
numRedblink=Serial.parseInt();

}

void loop() {

Serial.println(Bluemesssage);
for (int j=1;j<=numBlueblink; j=j+1) {
Serial.print("You are on blink #:");
Serial.println(j);
digitalWrite(BlueLED,HIGH);
delay(BlueLEDontime);
digitalWrite(BlueLED,LOW);
delay(BlueLEDofftime);
}
Serial.println(" ");

Serial.println(Redmessage);
for (int i=1;i<=numRedblink; i=i+1) {
Serial.print("You are on blink #:");
Serial.println(i);
digitalWrite(RedLED,HIGH);
delay(RedLEDontime);
digitalWrite(RedLED,LOW);
delay(RedLEDofftime);
}
Serial.println(" ");

Here is what shows in my monitor:
Welcome to my program
Please input the bluelink times? (I did input 2 at here).
Please input the redblink times?
The Blue is Blinking!
You are on blink #:1
You are on blink #:2

The Red is Blinking!

The Blue is Blinking!
You are on blink #:1
You are on blink #:2

The Red is Blinking!

The Blue is Blinking!
You are on blink #:1
You are on blink #:2

The Red is Blinking!

The Blue is Blinking!
You are on blink #:1
You are on blink #:2

I hope the interface ask me input the number for redblink. But it doesn't. Don't know why.

Please read this paying close attention to item 6 about posting with tags.

Your code is incomplete.

Please remember to use code tags when posting code.

What have you got the Line ending set to in the Serial monitor ?

If you don't flush the input buffer, any line ending characters left over from entering the Blue number will be taken as the start of the Red number. You will then only have one second before the parseInt() times out and returns zero.

int BlueLED = 9;     //define blue red pin at 9
int BlueLEDontime = 100;
int BlueLEDofftime = 500;
int RedLED = 7;
int RedLEDontime = 100;
int RedLEDofftime = 500;
int numBlueblink;
int numRedblink;
String Bluemesssage = "The Blue is Blinking!";
String Redmessage = "The Red is Blinking!";


void setup()
{
  Serial.begin(115200);
  Serial.println(F("Welcome to my program"));


  pinMode(BlueLED, OUTPUT);
  pinMode(RedLED, OUTPUT);


  // Flush the input buffer
  while (Serial.available())
  {
    Serial.read();
  }
  Serial.println("Please input the bluelink times:");
  // Wait for data to be available
  while (!Serial.available()) { }
  numBlueblink = Serial.parseInt();


  // Flush the input buffer
  while (Serial.available())
  {
    Serial.read();
  }
  Serial.println("Please input the redblink times:");
  while (!Serial.available()) { }
  numRedblink = Serial.parseInt();


}


void loop()
{
  Serial.println(Bluemesssage);
  for (int j = 0; j < numBlueblink; j++)
  {
    Serial.print("You are on blink #:");
    Serial.println(j+1);
    digitalWrite(BlueLED, HIGH);
    delay(BlueLEDontime);
    digitalWrite(BlueLED, LOW);
    delay(BlueLEDofftime);
  }
  Serial.println(" ");


  Serial.println(Redmessage);
  for (int i = 0; i < numRedblink; i++)
  {
    Serial.print("You are on blink #:");
    Serial.println(i+1);
    digitalWrite(RedLED, HIGH);
    delay(RedLEDontime);
    digitalWrite(RedLED, LOW);
    delay(RedLEDofftime);
