Hall Effect Sensor and Servo Problem

So I'm working on interfacing the sensor with the servo so that when a magnet is presented to the sensor it turn the servo and subsequently opens a door. Easy enough. However I keep getting an "expected declaration before '}' token" error. Not sure why. Here's code:

#include <Servo.h>

int inPin = 0;    // select the input pin for the Hall Effect Sensor
int servoPin = 2; // select the output pin for the Servo
int val = 0;       // variable to store the value coming from the sensor
int mean = 514;   // Value coming from Hall sensor when no mag introduced
int sensitivity = 1;
int minPulse     =  600;  // minimum servo position  
int maxPulse     =  2400; // maximum servo position  
int turnRate     =  100;  // servo turn rate increment (larger value, faster rate)  
int refreshTime  =  20;   // time (ms) between pulses (50Hz)  
int centerServo;         // center servo position  
int pulseWidth;          // servo pulse width    
long lastPulse   = 0; 

void setup() {
 pinMode(servoPin, OUTPUT);  // declare the ledPin as an OUTPUT
 pinMode(inPin, INPUT);
 centerServo = maxPulse - ((maxPulse - minPulse)/2);  
  pulseWidth = centerServo; 
}

void loop() {
    
 val = analogRead(inPin);  // read the Hall Effect Sensor
 if (val == mean){
   pulseWidth = centerServo;// If no signal from Hall Sensor, center the servo
    }
 
 if (val >= (mean + sensitivity) || val <= (mean - sensitivity)) {
   pulseWidth = pulseWidth + turnRate;
    if (millis() - lastPulse >= refreshTime) { 
    digitalWrite(servoPin, HIGH);   // start the pulse  
    delayMicroseconds(pulseWidth);  // pulse width  
    digitalWrite(servoPin, LOW);    // stop the pulse  
    lastPulse = millis();           // save the time of the last pulse  
     }

   }
   
   
  }
}

Thanks.

remove one of the closing brackets ( } ) at the end of loop.

If you move the cursor over the brackets in the IDE, it will show you the matching bracket. You can use this to help make sure that all your brackets match correctly
