error code. not name a type

right after my first while loop I enter numRedBlink the arduino isn't recognizing it. my error code says numRedBlink does not name a type. But in following this programmer on youtube learning what I can and on his arduino uno it recognized it. heres my code maybe you can help.

int redLedPin=9; //Declaring red led as an int, and set to 9:
int yellowLedPin=10; // Declaring yellow led as an int, and set to 10:
int redOnTime=250; //Red led is on 250:
int redOffTime=250; // Red led is off 250:
int yellowOnTime=250; // Yellow led is on 250:
int yellowOffTime=250; // Yellow led is off 250:
int numRedBlink; // declaring a variable
int numYellowBlink; // declaring a variable
String redMessage= "the red led is blinking"; // declaring a string variable
String yellowMessage= "the yellow led is blinking"; // declaring a string variable

void setup() {
Serial.begin(9600);
String wm1 ="hello nicholas "; // declare string variable
String wm2="its your program";
String wm3; // declare a sting variable
wm3=wm1+wm2; //concatenation take wm1+wm2=wm3
Serial.println(wm3);
pinMode(redLedPin,OUTPUT);
pinMode(yellowLedPin,OUTPUT);

}

void loop() {
Serial.println("How Many Times I Want Red LED To Blink"); // asking
while (Serial.available()==0) { } // wait for input.
}
numRedBlink=Serial.parseInt();
Serial.println("How Many Times I Want Red LED To Blink"); // asking
while [Serial.available()==0] { } // wait for input
}
numYellowBlink=Serial.parseInt();
int c=c+1;
Serial.println(redMessage);
for (c=1; c<=numRedBlink; c=c+1){ // starting for loop
Serial.print("I am Awsome");
Serial.println(c);
digitalWrite(redLedPin,HIGH); // turn the red led on:
delay(redOffTime); // wait:
digitalWrite(redLedPin,LOW); // turn the red led off:
delay(redOffTime); //Wait:
}
Serial.println(" ");
Serial.println(yellowMessage);
for (int c=1; c<=numYellowBlink; c=c+1){
Serial.print("i am awsome");
Serial.println(c);
digitalWrite(yellowLedPin,HIGH); //turn the yellow led on:
delay(yellowOffTime); //Wait:
digitalWrite(yellowLedPin,LOW); //turn the yellow led off:
delay(yellowOffTime); //Wait:
Serial.println(" ");
}
}

You have a curly brace too many after the while. That additional curly indicates the end of the loop() to the compiler.

Next time, please post code between code tags so it shows as below

 your code here

thank you

By the way, there seem to be more errors; e.g. why does thst while hve square brackets? I guess a book on C eould be a good investment :wink:

You have an several extra } in your loop section and it is not seeing the rest of the code.

If you use auto format you could see that.
Every '{' must end with one '}' and every '(' must end with a ')'. They must be evenly matched.

you can try this. I don't know if it does what you expect but it will compile.

int redLedPin = 9; //Declaring red led as an int, and set to 9:
int yellowLedPin = 10; // Declaring yellow led as an int, and set to 10:
int redOnTime = 250; //Red led is on 250:
int redOffTime = 250; // Red led is off 250:
int yellowOnTime = 250; // Yellow led is on 250:
int yellowOffTime = 250; // Yellow led is off 250:
int numRedBlink; // declaring a variable
int numYellowBlink; // declaring a variable
String redMessage = "the red led is blinking"; // declaring a string variable
String yellowMessage = "the yellow led is blinking"; // declaring a string variable

void setup() {
  Serial.begin(9600);
  String wm1 = "hello nicholas "; // declare string variable
  String wm2 = "its your program";
  String wm3; // declare a sting variable
  wm3 = wm1 + wm2; //concatenation take wm1+wm2=wm3
  Serial.println(wm3);
  pinMode(redLedPin, OUTPUT);
  pinMode(yellowLedPin, OUTPUT);

  numYellowBlink = Serial.parseInt();
  int c = c + 1;
  Serial.println(redMessage);
