Help with Javascript Homework

Hi,
I have been struggling with this code for three days. My teacher wants the layout to be like it is and there is a way to make it work that way but I am at a loss as to how to do it. She wants the function to be in the heading and the input for the function to be in the body and the button is supposed to calculate the Final Course Grade. I've tried two debuggers (firefox and PSpad) and they both get stuck on the Name not being defined. There are other errors to be sure.

Code:

<html>
<head>
  <title> Find Your Grade Here!!!!one!eleven! </title>
    <script type="text/javascript">
      // Assumes: Each box has a numerical value
      // Results: Calculates Final Grade and gives a message with Name 
      // and Ginal Pourse Frade.
      function GPA (HomeworkAverage,LabAverage, MidtermAverage,FinalExamGrade)
      function 
     {    
	     alert(Name);
	       var FinalCourseGrade =(HomeworkAverage*0.25 +LabAverage*0.20 + 
          MidtermAverage*0.25 +FinalExamGrade*0.30);
          var Name = document.getElementByID('Nbox');
          message = "Hello " + Name + ", " <br>
				 "According to your input, " <br>
				 "Your Homework Average Was: " + HomeworkAverage + " "<br>
				 "Your Lab Average Was: " + LabAverage + " "<br>
				 "Your Midterm Average Was: " + MidtermAverage + " "<br>
				 "Your Final Exam Grade Was: " + FinalExamGrade + " "<br>
				 "Therefore, Your Final Course Grade is: " + FinalCourseGrade  + " ";
		    return message;
      }
         </script>
	  <p>

<body>
  <hr>
    <p>
    Enter Name:
    <input type="text" id="Nbox" size="25" value="Johnathon Reinier" />
    Enter Homework Average:
    <input type="text" id="HWAbox" size="4" value="98" />
    Enter Lab Average:
    <input type="text" id="LAbox" size="4" value="97" />
    Enter Midterm Average:
    <input type="text" id="MAbox" size="4" value="87" />
    Enter Final Exam Grade:
    <input type="text" id="FEbox" size="4" value="105" />
    </p>

    <p>
    <input type="button" value="FinalCourseGrade"
	     onclick= Name = document.getElementbyId('Nbox').value;
                         Name = parseFloat(Name);
		         HomeworkAverage =  document.getElementbyId('HWAbox').value;
			 HomeworkAverage = parseFloat(HomeworkAverage);
			 LabAverage = document.getElementbyId('LAbox').value;
			 LabAverage = parseFloat(LabAverage);
			 MidtermAverage = document.getElementbyId('MAbox').value;
			 MidtermAverage = parseFloat(MidtermAverage);
			 FinalExamGrade = document.getElementbyId('FEbox').value;
			 FinalExamGrade = parsefFloat(FinalExamGrade);
			 Function GPA (HomeworkAverage, LabAverage, MidtermAverage, FinalExamGrade);
			 FinalCourseGrade = parseFloat(FinalCourseGrade);/>
	   </p>
