   	public static void main(String[] args)
   	{
      		GradeCalculator application = new GradeCalculator();
   
	
	
	   		application.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		}
		
	 public void enterJButtonActionPerformed(ActionEvent event)
	{
	{
	
	   scoreAmount = JOptionPane.showInputDialog("Number of Scores to be entered?");
		numberOfScores = Integer.parseInt(scoreAmount);
	   	
    }
	 
	 for (counter = 0;counter < numberOfScores;counter++)
	 {
	   gradeScore = JOptionPane.showInputDialog("Enter score");
		scoreValue = Integer.parseInt(gradeScore);
		scoreAccumulator += scoreValue;
		calculateAverage();
	 }
    }
	 
	 public void calculateAverage()
	 {
	  if 
	  (averageScore >= 89) {lastGrade = 'A';} 
	  else if 
	  (averageScore >= 79) {lastGrade = 'B';} 
	  else if 
	  (averageScore >= 69) {lastGrade = 'C';} 
	  else if 
	  (averageScore >= 64) {lastGrade = 'D';} 
	  else 
	  {lastGrade = 'F';}
	  displayGrade();	 
	 }
	 
	 public void displayGrade()
	 {
	 gradeJTextField.setText("" + (lastGrade));

	 }

Its a grade calculator, It compiles and runs but the only grade it outputs is an F. This is my entire main method. It seems to me like it should work. But I dont know, if i change averageScore to scoreAccumulator, i get it to output an A but no other scores, Also it grades after the first score is entered. Cant figure out where the problem is.

Did you consider finding out what the value of the averageScore variable is when you try to figure out the grade level? (Hint: print it out and look at what gets printed.) My prediction is that the value is zero, since I don't see any code which assigns it a value anywhere in your post, but obviously there's other code you haven't posted because I don't see a declaration for averageScore.

oh duh, i had it declared as. averageScore = scoreAccumulator. not averageScore = scoreAccumulator / numberOfItems.

Thanks.
