javascript - Cannot figure out why button is not showing -


i have button submit answers go on next question on quiz app. when try put in div quiz @ button disappears. doing wrong? appreciated.

here code:

var quizapp = quiz(questions, $('#quiz-area'));      quizapp.questiondisplay(); // currentquestion = 0, valid question      $('#next').on('click', quizapp.nextquestion);  $('#totalquestions').text(questions.length);      // todo: add event listener reset  $('#reset').on('click', quizapp.reset);
#quiz-area{  margin: 150px 160px;  padding: 100px 40px 40px 40px;  width: 500px;  height: 400px;  background-image: url("http://hardwoodhustle.com/wp-content/uploads/2014/03/hwh-bg1.jpg");    background-repeat: no-repeat;  -webkit-background-size: cover;  -mox-background-size: cover;  -o-background-size: cover;  background-size: cover;  }    div #quiz-area{  border: red 1px solid;  }    #quiz-area ul {  border: 1px solid red;  }    #quiz-area li,  #quiz-area ul {  list-style-type: none;  padding-left: 0;  }
<div id="quiz-area">  <div id="next">      	<button id="next" type="submit">submit answer</button>  	<div id="score"><span id="correct">0</span>/<span id="totalquestions">20</span></div>  </div>  </div>

<div id="quiz-container">         <div id="quiz-area"></div>     <div id="score">         <span><button id="next" type="submit">submit answer</button></span>         <span id="score-board"><span id="correct">0</span>/<span id="totalquestions">20</span></span>     </div> </div>
