Hi.
Why will it not run when I uncomment lines 18 & 19?
#define leds
#define green_led 11
#define yellow_led 10
#define red_led 9
int i = 0; //green
int j = 0; //yellow
int k = 0; //red
//line 10
void setup(leds) {pinMode(green_led, OUTPUT);pinMode(yellow_led, OUTPUT);pinMode(red_led, OUTPUT);}
void loop(leds){
////green led in & out
for (i = 0; i < 255; i++) {analogWrite(green_led, i);delay(10);}
for (i = 255; i > 0; i--) {analogWrite(green_led, i);delay(10);}
////yellow led in & out
// for (j = 0; j < 255; j++) (analogWrite(yellow_led, j);delay(10);)
// for (j = 255; j > 0; j--) (analogWrite(yellow_led, j);delay(10);)
//line 20
for (j = 0; j < 255; j++) {analogWrite(yellow_led, j);delay(10);}
for (j = 255; j > 0; j--) {analogWrite(yellow_led, j);delay(10);}
////red led in & out
for (k = 0; k < 255; k++) {analogWrite(red_led, k);delay(10);}
for (k = 255; k > 0; k--) {analogWrite(red_led, k);delay(10);}
;}
It works great, but when I uncomment lines 18 & 19. This is what I get:
leds_fade.cpp: In function 'void loop()':
leds_fade:17: error: expected )' before ';' token leds_fade:17: error: expected primary-expression before ')' token leds_fade:17: error: expected ;' before ')' token
leds_fade:18: error: expected ;' before ')' token leds_fade:18: error: expected primary-expression before ')' token leds_fade:18: error: expected ;' before ')' token
leds_fade:20: error: expected `;' before ')' token
I'm not sure if it wants a ); or a 
I have version 1.0.1 of the software, and I'm using an Uno.
