Compilation error: 'else' without a previous 'if'

I have written a very simple piece of code that lights a white LED when a button is pressed. I want the button state to be stored so the LED remains on until I press the button again.

I get the following error: Compilation error: 'else' without a previous 'if'

I can't work out where its gone wrong:

int whiteledPin = 8;
int buttonPin = 4;
int lastState = digitalRead(4);

void setup() {
  Serial.begin(9600);
  pinMode(buttonPin, INPUT_PULLUP);
  pinMode(whiteledPin, OUTPUT);

}

void loop() {
  int currState = digitalRead(buttonPin);
  if (currState == LOW); {
    digitalWrite(whiteledPin, HIGH);
  }
  else {
    digitalWrite(whiteledPin, LOW);
  }
  lastState = currState;
}

get rid of the semicolon

the syntax is

if (condition) {
  •••
} else {
  •••
}
