Hi there

can anyone help me correct this code please?
as i am getting the following error:
C:\Users\steve\Downloads\sketch_mar17a\sketch_mar17a.ino: In function 'void loop()':
C:\Users\steve\Downloads\sketch_mar17a\sketch_mar17a.ino:16:43: error: expected primary-expression before ';' token
16 | static unsigned long buttonPressStart = ; // Initialize to
| ^

exit status 1

Compilation error: expected primary-expression before ';' token

#include <BleKeyboard.h>

BleKeyboard bleKeyboard("ESP32-Keyboard2", "Me", 100);

#define BUTTON_PIN 4
#define LONG_PRESS_DURATION 100 // Duration for long press in milliseconds

void setup() {
pinMode(BUTTON_PIN, INPUT_PULLUP);
Serial.begin(115200);
Serial.println("Starting BLE work!");
bleKeyboard.begin();
}

void loop() {
static unsigned long buttonPressStart = ; // Initialize to
static bool buttonPressed = false;

// Read the button state
bool buttonState = digitalRead(BUTTON_PIN) == LOW;

if (buttonState && !buttonPressed) {
// Button is pressed
buttonPressed = true;
buttonPressStart = millis(); // Record the time when the button was pressed
}
else if (!buttonState && buttonPressed) {
// Button is released
buttonPressed = false;

unsigned long pressDuration = millis() - buttonPressStart; // Calculate press duration

if (pressDuration >= LONG_PRESS_DURATION) {
  // Long press detected  
  Serial.println("Rewind 10 seconds");
  bleKeyboard.write(KEY_LEFT_ARROW); // Simulating rewind  
} else {
  // Short press detected  
  Serial.println("Play/Pause");
  bleKeyboard.write(KEY_MEDIA_PLAY_PAUSE); // Simulating play/pause  
}

}

delay(50); // Small delay to debounce
}

UPDATE
I NOW HAVE THIS CODE WORKING FOR 2 SWITCHES (Written by ai!)

#include <BleKeyboard.h>

BleKeyboard bleKeyboard;

const int pausePlayButton = 14; // GPIO pin for Pause/Play button
const int rewindButton = 27; // GPIO pin for Rewind button

void setup() {
Serial.begin(115200);
pinMode(pausePlayButton, INPUT_PULLUP); // Set button pin as input with pull-up
pinMode(rewindButton, INPUT_PULLUP); // Set button pin as input with pull-up
bleKeyboard.begin();
}

void loop() {
if (digitalRead(pausePlayButton) == LOW) { // Check if Pause/Play button is pressed
bleKeyboard.write(KEY_MEDIA_PLAY_PAUSE); // Send Play/Pause command
delay(200); // Debounce delay
}

if (digitalRead(rewindButton) == LOW) { // Check if Rewind button is pressed  
    bleKeyboard.write(KEY_LEFT_ARROW); // Send Previous Track command  
    delay(200); // Debounce delay  
}

}

Try to fix as below:
static unsigned long buttonPressStart = 0; // Initialize to zero
