error: missing terminating ' character

hi, learning to use it Arduino. my first interest is Infrared Sensors. i have PIR Sensor Module SE-10. i got code but uploading to I/O board getting message: error: missing terminating ' character.

how to make it work?

code what i have:

' // example for the PIR motion sensor SE-10
'
' int timer = 500;
' int alarmPin = 0;
' int alarmValue = 0;
' int ledPin = 11;

' void setup () {
' Serial.begin (9600);
' pinMode(ledPin, OUTPUT);
' pinMode(alarmPin, INPUT);
' delay (2000); // it takes the sensor 2 seconds to scan the area around it before it can
' detect infrared presence.
' }

' void loop (){
' alarmValue = analogRead(alarmPin);

' if (alarmValue < 100){
' blinky(); // blinks when the motion has been detected, just for confirmation.
' }
' delay(timer);

' Serial.println (alarmValue);

' delay (10);

' }

' void blinky() {
' for(int i=0; i<3; i++) {
' digitalWrite(11,HIGH);
' delay(200);
' digitalWrite(11,LOW);
' delay(200);
' }
' }

For some reason you have a single-quote character at the beginning of every non-blank line in your sketch. They shouldn't be there. (none of them. There should be no single quotes in that entire sketch!) (Perhaps it was cut&pasted from some web page and internal formatting characters were accidentally copied along with the text itself.)

yes, thank you! it went well with uploading. cheers!
