"Missing Return Statement" although the return statement IS there?

Question

Hello :) I am currently studying computing science at staffordshire university, java is one of my modules (first year) and im about half way through (still at introduction stage though)... Within my code apparently I have not returned a statement... yet to my believe the return statement is there and in the correct space, i would appreciate it if you could have a look and tell me where I am going wrong please:
import java.util.*;
public class ReadWriteArrayApp3
+{+
+ public static void main(String [ ] args)+
+ {+
+ int[] nums = int double[6];+
+ double result;+
+ readArray(nums);+
+ printArray(nums);+
+ printReverse(nums);+
+ averageArray(nums);+
result = averageArray(nums);
+ System.out.println("The average of your numbers is " + result);+
+ } // end main+
public static void readArray(int [] a)
+ {+
+ Scanner kybd = new Scanner(System.in);+
+ System.out.println("Please enter 6 Integers");+
+ for(int i=0; i < a.length; i++)+
+ {+
+ a[i] = kybd.nextInt();+
+ }+
+ }+
+public static void printArray(int [ ] b)+
+ {+
+ for (int i = 0; i < b.length; i++)+
+ {+
+ System.out.println(b);+
+ }+
+ }+
+ public static void printReverse(int [ ] c)+
+ {+
+ for (int i = c.length-1; i >= 0; i--)+
+ {+
+ System.out.println(c[i]);+
+ }+
+ }+
+ public static double averageArray(int [ ] d)+
+ {+
+ double sum, tot, average;+
+ for (int i = 0; i < d.length; i++)+
+ {+
+ tot = tot + d[i];+
+ average = (tot)/d.length;+
+ if ((average)=(tot/d.length))+
+ {+
+ sum = average;+
+*  }
+ return sum;+
+ }+
+} // end application class+
Console states:
javac  ReadWriteArrayApp3.java
ReadWriteArrayApp3.java:49: missing return statement
* ^*
*1 error*
Above in the code I have shown I have made a part bold... this shows the area in which console has a problem with.
I would really appreciate any help in which I get
Thankyou
Victoria

import java.util.*;

     public static void main(String [ ] args)
          int[] nums = int double[6];
          double result;
          readArray(nums);
          printArray(nums);     
          printReverse(nums);
          averageArray(nums);
          result = averageArray(nums);
          System.out.println("The average of your numbers is " + result);
     }  //  end main
     public static void readArray(int [] a)
          Scanner kybd = new Scanner(System.in);
          System.out.println("Please enter 6 Integers");
          for(int i=0; i < a.length; i++)
          a[i] = kybd.nextInt();
     public static void printArray(int [ ] b)
          for (int i = 0; i < b.length; i++)
               System.out.println(b);
     public static void printReverse(int [ ] c)
          for (int i = c.length-1; i >= 0; i--)
               System.out.println(c[i]);
     public static double averageArray(int [ ] d)
          double sum, tot, average;
          for (int i = 0; i < d.length; i++)
               tot = tot + d[i];
               average = (tot)/d.length;
               if ((averagetot)=(tot/d.length))
                    sum = average;
     return sum;
} // end application class*line 49 is bold*
