title: passed variable becomes undefined javascript
body: <p>I have 2 function that do that same thing.  One works and one doesn't.</p>
  
  <pre><code>function showHideRedrawAttendanceAvg(chart, dataType)
  {
      $("#attendanceCount").addClass("hide");
      $("#attendanceAvg").removeClass("hide");
      redrawAttendance(chart, dataType);//Parameters are defined
  }
  
  function redrawAttendance(chart, dataType) //Parameters are passed and are defined
  {
      //Some logic
  }
  
  //I tried change the parameter name several times to make sure it was unique
  function showHideRedrawAttendanceCount(agagfadfg)
  {
      $("#attendanceAvg").addClass("hide");
      $("#attendanceCount").removeClass("hide");
      redrawAttendanceTree(agagfadfg);//Parameter is defined
  }
  
  function redrawAttendanceTree(agagfadfg)//Parameter becomes undefined
  {
      //Some logic
  }
  </code></pre>
  
  <p>I have no idea why the two functions behave differently.  I even removed all of my javascript from the file and just left the showHideRedrawAttendanceCount and redrawAttendanceCount functions and it still did not work.</p>
