I finished typing the code and then connected the board, verified and uploaded the code but this came up. Any help is greatly appreciated. Thanks!
Arduino: 1.6.8 (Mac OS X), Board: "Arduino/Genuino Uno"
Sketch uses 1,248 bytes (3%) of program storage space. Maximum is 32,256 bytes.
Global variables use 11 bytes (0%) of dynamic memory, leaving 2,037 bytes for local variables. Maximum is 2,048 bytes.
avrdude: ser_open(): can't open device "COM1": No such file or directory
ioctl("TIOCMGET"): Inappropriate ioctl for device
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

// this is a comment
if (switchState == LOW) {
// the button is not pressed
digitalWrite(3, HIGH); // green LED
digitalWrite(4, LOW); // red LED
digitalWrite(5, LOW); // red LED
}
else { // the button is pressed
digitalWrite(3, LOW);
digitalWrite(4, LOW);
digitalWrite(5, HIGH);
delay(250); // wait for a quater second
// toggle the LEDs
digitalWrite(4, HIGH);
digitalWrite(5, LOW);

}
} // go back to the begining of the loop
