rewrote this :

boolean compare = true; 
const int anPin = A5;
int ledPin = 9;    // LED connected to digital pin 9
int fadeValue;
void setup()  { 
   Serial.begin(9600); // nothing happens in setup 

  pinMode(anPin, INPUT);
} 

void loop()  { 
int   avRead = analogRead(anPin);    //11-25 values
 Serial.println(avRead);
 delay(100);
 


  
if(avRead > 15){
  if (compare = true){
 for (int fadeValue = 0 ; fadeValue <= 255; fadeValue +=5) {  //<< need a bracket here
 analogWrite(ledPin, fadeValue);
 
delay(30);
 

 }
 compare = !compare;
 
 }
 else if (avRead< 15){
   if (compare = !compare){
    for (int fadeValue = 255 ; fadeValue >= 0; fadeValue -=5) {  
   analogWrite(ledPin, fadeValue);
   delay(30);
}}}}}
