Arduino Board Error

Hej jeg sidder og leger med et arduino board, og får den her fejl når jeg prøver at oploade til boardet.

error: expected unqualified-id before 'if'

Koden er

#define LED 9 // the pin for the LED
#define BUTTON 7 // input pin of the pushbutton

int val = 0;  // store the state of the input pin

int old_val = 0; // store the previos of the input pin
int state = 0; // 0 = LED off while 1 = LED on

int brightness = 128; // stores the brightness value
unsigned long startTime = 0; // when did we begin pressing?

void setup() {
  pinMode(LED, OUTPUT); // tell Arduino LED is an output
  pinMode(BUTTON, INPUT); // and BUTTON is an input
}

void loop() {
 
  val = digitalRead(BUTTON); // read input value and store it
                            // yum, fresh
 
  // check if there was a transition
  if ((val == HIGH) && (old_val == LOW)) {
   
    state = 1 - state; // change the state from off to on
                      // or vice-versa
   
    startTime = millis(); // millis() is the Arduino clock
                          // it returns how many milliseconds
                          // have pressed since the board has
                          // been reset.
   
    // (this line remebers when the button
    // was last pressed)
    delay(10);
  }
}

  // check whether the button is being held down
    if ((val == HIGH) && (old_val == HIGH)) {
 
    // if the button is held for more then 500ms.
    if (state == 1 && (millis() - startTime) > 500) {
     
      brightness++; //increment brightness by 1
      delay(10);
     
     
      if (brightness > 255) { // 255 is the max brightness
     
        brightness = 0; //if we go over 255
                        // let´s go back to 0
      }
    }
  }
   
    old_val = val; // val is now old, let´s store is
   
    if (state == 1) {
      analogWrite(LED, brightness); // turn LED ON at the
                                    // current brightness level
    } else {
      analogWrite(LED, 0); // turn the LED OFF
     
    }
  }

Mit board er et Diecimila

Håber der er nogle derude der kan hjælpe mig
