Need Help!!! Can someone please point out my errors?!?!?!?

int photocellPin = 0; //cell and 10k pulldown are connedted to A0
int photocellReading; // analog reading from the analog resistor divider

void setup(void) {
// We’ll send debugging information via the Serial Monitor
Serial.begin(9600);
}

void loop(void) {
photocellReading = analogRead(photocellPin)

Serial.print("Analog reading = ") ,
Serial.print(photocellReading) ; //the raw analog reading

// We’ll have a few threshholds, qualitatively determined
if (photocellReading < 10) {
Serial.println(" - Dark");
} else if (photocellReading < 400) {
Serial.println(" - Dim") ;
} else if (photocellReading < 600) {
Serial.println(" - Light") ;
} else if (photocellReading < 800 {
Serial.println(" - Bright") ;
} else {
Serial.println(" - Very bright") ;
}
delay(1000) ;
}

Errors
ldr_test.cpp: In function ‘void loop()’:
ldr_test:11: error: expected ;' before 'Serial' ldr_test:21: error: expected )’ before ‘{’ token

Please edit your post, select the code, and put it between [code][/code] tags.

You can do that by hitting the # button above the posting area.

  Serial.print("Analog reading = ") ,

Comma should be a semicolon.

} else if (photocellReading < 800  {

And a ) after the 800…

(Both errors were actually explained in the error messages… just a matter of finding the right line 8) )

   photocellReading = analogRead(photocellPin);    // semi-colon

  Serial.print("Analog reading = ");   // semi-colon
