I'm not sure how to tackle this...

I'm not entirely sure how to go about solving this error?

using System;

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

      while (keepGoing)
      {

      // Prompt the user for minutes exercised
      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.");
        }
       else if(minutes == 10)
       {
          Console.WriteLine("Better than nothing, am I right?");
       }
        else if(minutes <= 30)
        {
          Console.WriteLine("Way to go hot stuff!");
        }
        else if(minutes <= 60)
        {
        Console.WriteLine("You must be a ninja warrior in training!");
        }
        else
        {
          Console.WriteLine("Okay, now you're just showing off!");
        }
      }
           catch(FormatException)
        {
          Console.WriteLine("That is not valid input.");
          continue;
        }

      }



      // Add minutes exercised to total
      runningTotal = runningTotal + minutes; // this is line 56

      // Display total number of exercised to the screen
      Console.WriteLine("you've entered " + runningTotal + " minutes");


      // Repeat until the user quits

    Console.WriteLine("Goodbye");
      }
  }

}

To address the first error at line 19, you need to add () at the end of ToLower such as:

      if (entry.ToLower() == "quit")

The second error is because you have a couple misplaced lines. Move lines 55 to 59 under line 43. This way they are in your try block. It should look something like this:

          Console.WriteLine("Okay, now you're just showing off!");
        }
        // Add minutes exercised to total
        runningTotal = runningTotal + minutes; // this is line 56

        // Display total number of exercised to the screen
        Console.WriteLine("you've entered " + runningTotal + " minutes");
      }
        catch(FormatException)
