Cannot solve try/catch Code Challenge.

I cannot complete the challenge for this video. I tried in different ways, but I'm just stuck.

Here's some general hints:

There are several issues with the provided code that need fixing. Some things to remember:

  • a variable should only be declared once
  • a variable should be declared in the outermost scope it is used in
  • a variable already declared can be assigned any number of times

I looked at the code in the challenge. It shows that input was used, but it was never declared. In order to use it, you must first give it a type in its instantiation, like:

string variablename = Console.ReadLine();
