Thread: I am a newbie and I am stuck PLEASE HELP!!!

I am trying to validate that a user input valid information at the prompt but I keep getting errors please help!
Here is my code:

    private double computeAverageSales() {
        WebHost webHost;
        double average = 0;
        double total = 0;
        int counter = 0;
 
 
        for (int i = 0; i <= 0; i++) {
            while (true) {
                do {
                    System.out.print("Please enter the price of the new package: $");
 
                    while (!scanner.hasNextDouble()) {
                        System.out.println("Please enter a postive number!");
                        scanner.next();
                    }
 
                    double webHostPrice = scanner.nextDouble();
                    total = webHostPrice + total;
                    counter++;
                    while (webHostPrice <= 0) {
                        break;
                    }
                }
 
                    do {
                        System.out.print("What will be the product ID: ");
 
                        while (!scanner.hasNextInt()) {
                            System.out.print("Please enter a valid product ID!");

                                                       }
        }
    }

I know it is messy but that is me messing with it for three days please help.

Like I said I am new at this and I found the do{....}while{.....scanner.next();} online for validation
The error I am getting says "while expected" when I try to close the do statement

when I run the code this is the error I am getting
run:

Welcome to the Web Host Ordering System

Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - missing return statement

I changed the text color of the "while" section

do {
                        System.out.print("What will be the product ID: ");
 
                        [COLOR="#FFFF00"]while (!scanner.hasNextInt()) {
                            System.out.print("Please enter a valid product ID!");
                            scanner.next();                  
                        int webHostId = scanner.nextInt();
                        scanner.nextLine();
                        }[/COLOR]

--- Update ---

Yes I am using NetBeans and I get the red flag when I hover over it that is when it gives me the "While Expected" error

--- Update ---

Would you like for me to upload a compressed folder of the NetBeans project?
