Simple print sensor value code does not show values in serial monitor

I have followed all the steps in this tutorial and I am pretty sure it is not my code or my hardware that is the problem.

I cannot see any values on my screen.
The tutorial says:
"Now, when you open your Serial Monitor in the Arduino development environment (by clicking the button directly to the right of the "Upload" button in the header of the program), you should see a steady stream of numbers ranging from 0-1023, correlating to the position of the pot."

Well, the button to the right of upload is the new sketch button in my arduino program (mac os x) so I'm not sure if I am "in the arduino developer environment"

But I do see the serial monitor and it doesn't read any values when I test my pot after uploading the sketch.

void setup() {
Serial.begin(9600);
}

void loop() {
int sensorValue = analogRead(A0);
Serial.println(sensorValue, DEC);
delay(1);
}

What gives? Why can't I read the numbers off of my pot?

why does your code have "DEC" in it

Serial.println(sensorValue, DEC);

The example says the following:

Serial.println(sensorValue);

The serial monitor button is on the FAR right (edge of screen/window) looks like a square with a magnifying glass
