470 PointsI honestly didnt quite understand the error the video was talking about. Can someone explain it?
all is said
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
input = Console.ReadLine();
if (input == "quit")
{
string output = "Goodbye.";
}
else
{
string output = "You entered " + input + ".";
}
Console.WriteLine(output);
}
}
}

231,210 PointsThere are several errors to be fixed here.
I'm not sure what part of the video you are referring to, but your question links to a challenge where instead of writing code, you fix some that has problems. Things to bear in mind:
- variables should be declared (and optionally initialized) before they are used
- variables should be declared only once (but may be assigned multiple times)
- variables should be declared in the outermost scope in which they are used
- the Preview button is helpful for showing the compiler error messages
