將變量傳遞給Google Piechart

我試圖將變量傳遞到Google圖表中，但是當我這樣做時圖表停止顯示，我的目標是每次在輸入字段中輸入不同的數字但我現在只是沒有得到任何地方。這是我的，有人可以請提供一些指導我做錯了什麼？將變量傳遞給Google Piechart

的Javascript

<script type="text/javascript" src="https://www.google.com/jsapi"></script> 

    <script type="text/javascript"> 
     google.load('visualization', '1', {packages: ['corechart']}); 
    </script> 

    <script type="text/javascript"> 
     function numbers(){ 
      var work_field = document.forms['work_form']['work_n_field'].value; 
      var work_div = document.getElementById('number-work'); 
      var numberschart = work_div.innerHTML = work_field; 
      return false; 
     }; 

     function drawVisualization() { 
      // Create and populate the data table. 
     var data = new google.visualization.DataTable(); 
     data.addColumn('string', 'Task'); 
     data.addColumn('number', 'Hours per Day'); 
     data.addRows(5); 
     data.setValue(0, 0, 'Work'); 
//Right here is where I pass my variable into the chart 
     data.setValue(0, 1, numberschart); 
//And I leave the rest here until I define more input field. 
     data.setValue(1, 0, 'Eat'); 
     data.setValue(1, 1, 2); 
     data.setValue(2, 0, 'Commute'); 
     data.setValue(2, 1, 2); 

     // Create and draw the visualization. 
     new google.visualization.PieChart(document.getElementById('visualization')). 
      draw(data, { 
      title:"Mortgage Rates", 
      colors: ['#a4b12d', '#818e0a', '#5c6601', '#f0fd79', '#dbe864'], 
      }); 
     }  
     google.setOnLoadCallback(drawVisualization); 
    </script>

的Html

<div id="visualization" style="width: 400px; height: 300px;"></div> 
    <form name="work_form" onsubmit="return numbers()"> 
    <label id="n-work-label">Work</label><input name="work_n_field"/> 
    <button name="submit" id="submit" value="submit" onclick="numbers()">Submit</button> 
    </form> 
    <div id="number-work"></div> 
    </div>

任何幫助是極大的讚賞，感謝您

我也把它添加到爵士小提琴，但圖表添加到資源之時似乎沒有檢測到它。 http://jsfiddle.net/pkCCa/
