How to fix my sketch

Can anyone help me fix my sketch it keeps on saying ecpected to be at the end of input}
// Fading Light with button
const int LED = 9; // the pin for the LED
int i = 0; //usedbto count up and down
const int BUTTON = 7;
int val =0; //val will be used to store the state of the input pin
void setup() {
pinMode(LED, OUTPUT); //LED is a output
pinMode(BUTTON, INPUT); // and BUTTON is an INPUT
}
void loop()
{
val = digitalRead(BUTTON);//read input value and store it
//check whether the input is HIGH (button pressed)
if (val == HIGH) {
digitalWrite(LED, HIGH); //turn LED on
} else {
digitalWrite(LED, LOW);
}
{
for (i + 0; i < 255; i++) { // loop from 0 to 254 (fade in)
analogWrite(LED, i); // set the LED brightness
delay(10); // waits 10ms
}
for (i = 255; i > 0; i–){ // loop from 255 to 1 (fade out)
analogWrite(LED, i); // set the LED brightness
delay(10);} //wait 10ms
}

Thankyou

You need one more } at the end of the code to finish up void loop.

If you use CTRL-T, it will tell you that there is one missing.
