Show correct or wrong answer in javascript by if or else statement

I'm working on Javascript and want to show the correct answer when someone clicks on a wrong option. Here is my code

 function processQuestion(choice){
    var bgcolor = '';
    var explanationhtml = '';
    if(quiz.questions[currentquestion]['choices'][choice] == quiz.questions[currentquestion]['correct']){
        bgcolor = '#8AFC7F';
        explanationhtml = '<div class="outcome-headline correct-text"> <i class="glyphicon glyphicon-ok"></i>'+quiz.questions[currentquestion]['correct']+'</div> ';
        score++;
    } else {

        var correct=quiz[currentquestion]['correct'];

    $('li.choice:contains('+correct+')').css('background-color', '#50D943');

         $('.choice').eq(choice).css({
             'background-color': '#D92623'
        explanationhtml = '<div class="alert alert-danger"><div class="outcome-headline incorrect-text"><i class="glyphicon glyphicon-remove"></i><strong>Sorry Wrong Answer!</strong> '+quiz.questions[currentquestion]['correct']+'</div></div> ';

Where did I go wrong?
