Help with arrays in C#

[crackersixx]

Sorry. My question was what is wrong with my code. Thank you for responding. I'm trying to figure out your answers. What do you mean out of scope? How do I fix it?

There really is too much wrong with your code to even bother trying to teach it all to you here.

static void Main(string[] args)
        {

            int[] sales = new int[9];
            int[] frequency = new int[9];

             for(int counter = 0; counter < 9; counter++)
             {
                Console.Write("Enter in the sales for the salesperson: ");
                sales[counter] = Int32.Parse(Console.ReadLine());
                
             }

             for (int counter = 0; counter < 9; counter++)
             {

                 frequency[(Convert.ToInt32((sales[counter] * .09)) - 1)] = (frequency[(Convert.ToInt32((sales[counter] * .09)) - 1)] + 1);
                 
             }

             int ranges = 200; 
             for (int counter = 0; counter < 9; counter++)
             {
                 Console.WriteLine(ranges.ToString() + "-" + Convert.ToString(ranges + 99) + ": " + frequency[counter].ToString());
                 ranges = ranges + 100;
             }
             Console.ReadLine();
        }

That should give you close to what you want, i'll have to charge you for any further customization
