Ive been trying to write a program that will ask for 5 test scores, give you the average of the scores and also the corresponding grade that goes with them, unfortunately the grade doesn't seem to post when called. Any help would be welcome.

import javax.swing.JOptionPane; //Needed for GUI
import java.text.DecimalFormat; //needed to format the Output


public class avg_Score_Anderson
{//Begin class
	public static void main(String[] args)
	{//Begin main method

		String inputString;   //For reader's input
		double Score1,       //Define score1
			   Score2,      //Define  score2
		 	   Score3,     //Define   score3
		   	   Score4,    //Define    score4
		 	   Score5,   //Define     score5
		       Average ;//Define      Average

DecimalFormat formatter = new DecimalFormat("#,##0.0"); //format the scores

		// Get the five scores
		inputString=
		  JOptionPane.showInputDialog("Enter the First Test Score: "); //ask user to enter the first test score
		Score1 = Double.parseDouble(inputString);

		inputString=
		  JOptionPane.showInputDialog("Enter the Second Test Score: ");//ask user to enter the second test score
		Score2 = Double.parseDouble(inputString);

		inputString=
		  JOptionPane.showInputDialog("Enter the third test score: ");//ask user to enter the third test score
		Score3 = Double.parseDouble(inputString);

		inputString=
		  JOptionPane.showInputDialog("Enter the fourth test score: ");//ask user to enter the fourth test score
		Score4 = Double.parseDouble(inputString);

		inputString=
		  JOptionPane.showInputDialog("Enter the fifth test score: ");//ask user to enter the fifth test score
		Score5 = Double.parseDouble(inputString);

	    // Call to method calcAverage and output the 5 test average
          Average = calcAverage(Score1, Score2, Score3, Score4, Score5);



		// Display Average test Score and Determine the letter grade for each test and call to determineGrade

				JOptionPane.showMessageDialog(null, "\t\nTest score one is : " +formatter.format(Score1)  +"\t Grade: " + determineGrade(Score1)
				                                  + "\t\nTest score two is : " +formatter.format(Score2)  +"\t Grade: " + determineGrade(Score2)
				                                  + "\t\nTest score three is : " +formatter.format(Score3)  +"\t Grade: " + determineGrade(Score3)
				                                  + "\t\nTest score four is : " +formatter.format(Score4)  +"\t Grade: " + determineGrade(Score4)
				                                  + "\t\nTest score five is : " +formatter.format(Score5)  +"\t Grade: " + determineGrade(Score5)
				                                  + "\n"
				                                  + "\t\nYour average test score is : " +formatter.format(Average) +"\t Grade: " + determineGrade(Average),
		                                            "\tYour Test Results",JOptionPane.INFORMATION_MESSAGE);

		}//end Main method

		// Calculate the average of the five test scores
		public static double calcAverage(double Score1, double Score2, double Score3, double Score4, double Score5)
		{
			double Average = ((Score1 + Score2 + Score3 + Score4 + Score5) / 5);
			return Average;
		}

		// Determine the letter grade for the average and 5 test scores
		public static double determineGrade(double Average)
		{
			char grade; // Define grade

			// Determine letter grade
			if (Average>=90)
			{
				grade = 'A';
