"try" and "catch"

Can't get this to run. Don't know what I did

using System;

namespace Treehouse.FitnessFrog//namespace { class Program//class { static void Main()//method {

    double runningTotal = 0;
    bool keepGoing = true;

    while(keepGoing)
    {
      //prompt user for minutes exercisesd
      Console.Write("Enter how many minutes you exercised or type \"quit\" to exit: ");
      string entry = Console.ReadLine();

      if (entry.ToLower() == "quit")
      {
        keepGoing = false;
      }
      else
      {


        try
        {
           double minutes = double.Parse(entry);
           if(minutes <= 0)

      {
        Console.WriteLine(minutes + " is not an accepatble value.");
        continue;
      }
      else if(minutes <= 10)
      {
        Console.WriteLine("Better than nothing");
      }
        else if(minutes<=30)
        {
          Console.WriteLine("Way to go");
        }
        else if(minutes <=60)
        {
          Console.WriteLine("Pizza tonight!");
        }
        else
        {
          Console.WriteLine("you are just showing off!");
         }  

        }
         runningTotal = runningTotal + minutes;
        {           

        catch(FormatException)
        {
          console.WriteLine("That is not valid input.");
          continue;
        }




      //add minutes exd to total


      Console.WriteLine("You entered " + runningTotal + " minutes");
      //Display total minutes exercised to the screen




      //repeat until user quits
      }
   }

 }

}

}

I'm seeing a few issues here:

  • the catch block should directly follow the try block
  • the catch block should be at the same level as the try block (not inside another block)
  • C# is case sensitive, so console.WriteLine needs to be Console.WriteLine
  • you were missing some ending braces (or had stray open braces)
  • acceptable was misspelled ("accepatble") :wink:

Here's the code with those issues repaired:

using System;

namespace Treehouse.FitnessFrog //namespace
{
    class Program               //class
    {
        static void Main()      //method
        {
            double runningTotal = 0;
            bool keepGoing = true;

            while(keepGoing)
            {
                //prompt user for minutes exercisesd
                Console.Write("Enter how many minutes you exercised or type \"quit\" to exit: ");
                string entry = Console.ReadLine();
                if (entry.ToLower() == "quit")
                {
                    keepGoing = false;
                }
                else
                {
                    try
                    {
                        double minutes = double.Parse(entry);
                        if(minutes <= 0)
                        {
                            Console.WriteLine(minutes + " is not an acceptable value.");
                            continue;
                        }
                        else if(minutes <= 10)
                        {
                            Console.WriteLine("Better than nothing");
                        }
                        else if(minutes <= 30)
                        {
                            Console.WriteLine("Way to go");
                        }
                        else if(minutes <= 60)
                        {
                            Console.WriteLine("Pizza tonight!");
                        }
                        else
                        {
                            Console.WriteLine("you are just showing off!");
                        }  
                        //add minutes exd to total
                        runningTotal = runningTotal + minutes;
                    }
                    catch(FormatException)
                    {
                        Console.WriteLine("That is not valid input.");
                        continue;
                    }
                    //Display total minutes exercised to the screen
                    Console.WriteLine("You entered " + runningTotal + " minutes");
                }
                //repeat until user quits
            }
        }

Try this to see if work in the catch part add a name of the variable FormatException 

catch(FormatException e) // <------- here
        {
          console.WriteLine("That is not valid input.");
          continue;
        }
