    <p>Been trying to solve this for 2 days now and I just can't get it to work! The programs layout has to stay the same (part of the challenge). Really bugging me and hoping somebody could shed some light...</p> <p>I keep getting the following error: Use of unassigned local variable 'countOfFizz'<br> Use of unassigned local variable 'countOfBuzz' Use of unassigned local variable 'countOfFizzBuzz' Use of unassigned local variable 'countOfPrime'</p> <p>On these lines: </p> <pre><code>fb.IsFizz(input, countOfFizz); fb.IsFizz(input, countOfBuzz); fb.IsFizz(input, countOfFizzBuzz); fb.IsFizz(input, countOfPrime); </code></pre> <p>and here is the full code. (again apologies if its poor coding, its basics and the layout has been supplied already).</p> <pre><code>class FizzBuzz { public static void Main() { int input; string enter; int countOfFizz; int countOfBuzz; int countOfFizzBuzz; int countOfPrime; Console.WriteLine("Please enter a number: "); enter = Console.ReadLine(); input = int.Parse(enter); while (input != 0) { Console.WriteLine("Please enter a number: "); enter = Console.ReadLine(); input = int.Parse(enter); FizzBuzz fb = new FizzBuzz(); fb.IsFizz(input, countOfFizz); FizzBuzz fb1 = new FizzBuzz(); fb1.IsBuzz(input, countOfBuzz); FizzBuzz fb2 = new FizzBuzz(); fb2.IsFizzBuzz(input, countOfFizzBuzz); FizzBuzz fb3 = new FizzBuzz(); fb3.IsPrime(input, countOfPrime); FizzBuzz fb4 = new FizzBuzz(); fb4.TotalFizz(countOfFizz); FizzBuzz fb5 = new FizzBuzz(); fb5.TotalBuzz(countOfBuzz); FizzBuzz fb6 = new FizzBuzz(); fb6.TotalFizzBuzz(countOfFizzBuzz); FizzBuzz fb7 = new FizzBuzz(); fb7.TotalPrime(countOfPrime); } Console.WriteLine("Finished."); } public bool IsFizz(int input, int countOfFizz) { if (input % 9 == 0) { Console.WriteLine("Fizz"); countOfFizz++; return true; } return false; } public bool IsBuzz(int input, int countOfBuzz) { if (input % 13 == 0) { Console.WriteLine("Buzz"); countOfBuzz++; return true; } return false; } public bool IsFizzBuzz(int input, int countOfFizzBuzz) { if (input % 9 == 0 &amp;&amp; input % 13 == 0) { Console.WriteLine("FizzBuzz"); countOfFizzBuzz++; return true; } return false; } public bool IsPrime(int input, int countOfPrime) { for (int i = 2; i &lt; input; i++) { if (input % i == 0 &amp;&amp; i != input) { return false; } } Console.WriteLine("Prime"); countOfPrime++; return true; } public void BeginTesting(int countOfFizz, int countOfBuzz, int countOfFizzBuzz, int countOfPrime) { countOfFizz = 0; countOfBuzz = 0; countOfFizzBuzz = 0; countOfPrime = 0; } public int TotalFizz(int countOfFizz) { Console.WriteLine("Number of Fizz: "); return countOfFizz; } public int TotalBuzz(int countOfBuzz) { Console.WriteLine("Number of Buzz: "); return countOfBuzz; } public int TotalFizzBuzz(int countOfFizzBuzz) { Console.WriteLine("Number of FizzBuzz: "); return countOfFizzBuzz; } public int TotalPrime(int countOfPrime) { Console.WriteLine("Number of Prime: "); return countOfPrime; } } </code></pre>

    1. COThe error is clear. You're *not initializing your `countOf` variables before you use them. You declare them, and then use them and increment the value, but they need to be initialized before you start using them. Please learn to actually **read** the words in the error message. They almost always mean something.

    2. CO_programs layout has to stay the same_ - Why? It's dreadful. Whoever set this really needs to go on a course themselves!

    3. COthe static void main is my own doing! all i got was a layout full of empty methods and had to do the rest myself!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
