Arduino interrupt not called using PinChangeInterrupt

I am new to Arduino and I was trying to figure out how to use an interrupt. When I ran this it would read my magnet but the interrupt would never be called and I couldn't figure out if anyone can help me that would be great.

Thanks.

Here is the code

#include <PinChangeInterrupt.h>

//#define INTERRUPT_PIN 12
#include <Math.h>

#define RADIUS 3
const int hallPin = 7; // the number of the hall effect sensor pin
const int ledPin =  13; // the number of the LED pin
// variables will change:
int hallState = 0; // variable for reading the hall sensor status
double inital_val = 0.0;
double distance = inital_val;

void setup() {
  // initialize the LED pin as an output:
  pinMode(ledPin, OUTPUT);
  pinMode(hallPin, INPUT);
  //attachInterrupt(hallPin, calc_distance, HIGH);
  // initialize the hall effect sensor pin as an input:
  attachInterrupt(digitalPinToInterrupt(hallPin), calc_distance , HIGH);
  Serial.begin(9600);
}

void loop() {
  //read the state of the hall effect sensor:
  hallState = digitalRead(hallPin);
  if (hallState == LOW) {
    // turn LED on:
    Serial.print("Main Loop: HallState LOW\n");
    digitalWrite(ledPin, HIGH);
    Serial.print(distance, 2);
    Serial.print("\n");
  } else {
    Serial.print("Main Loop: HallState HIGH\n");
    // turn LED off:
    digitalWrite(ledPin, LOW);
  }
}

void calc_distance() {
  Serial.print("INTERRUPT! \n");
  if (digitalRead(hallPin) == HIGH) {
    Serial.print("YES!\n");
    distance += PI * 2 * RADIUS;
  } else {
    Serial.print("NO!\n");
  }
}
