whats wrong with this for loop

keep getting an unexpected token += 

if(quiz.index == quiz.movies.length){

              for (i = 0; i < movies.length; i++){

            var x += '<p class="'+quiz.movies[i].right+'">'+quiz.movies[i].name+ ' real rating '+ quiz.movies[i].rating+'</p><br> ';
              }
                document.write(x)

You are declaring a variable inside the loop so it will be declared few times. 

if (quiz.index === quiz.movies.length) { // put '===' to be more specific - good practice

    var x; // declare it first, since you are appending a value to it it may contain 'undefined' when you declare it

    for (i = 0; i < movies.length; i++){


            x += '<p class="' + quiz.movies[i].right + '">' + quiz.movies[i].name + 
            ' real rating ' + quiz.movies[i].rating + '</p><br>';

    }


    document.write(x)

}
