I think the attached (can't attach? / posted below) should work, but am getting the message: Bummer! Did you add a catch block to handle the thrown exception?
Here’s the link: https://teamtreehouse.com/library/c-objects/inheritance/catching-exceptions-2
If incorrect, would like to understand why.
***** code *****
int value = int.Parse(Console.ReadLine());
if (value < 0 || value > 20)
{
throw new System.Exception();
}
try
{
Console.WriteLine(string.Format("You entered {0}", value));
}
catch (System.Exception)
{
Console.WriteLine("Value is out of bounds!");
}

So you just need to move the beginning of the try block up to include the if with the throw inside.

To anyone reading this with more coding knowledge than students at this level I may sound like an idiot but trust me, this question makes it quite unclear what's going on. Just some hopefully useful feedback from me.

You can make suggestions about a course directly to the staff as described on the Support page.

6,452 PointsOkay so now, I am actually getting the error message: "Bummer! I entered "25". I expected "Value is out of bounds!" but got "Value is out of bounds" instead."
What on earth am I supposed to do with that information??
int value = int.Parse(Console.ReadLine());
try { if (value < 0 || value > 20) { throw new System.Exception(); } Console.WriteLine(string.Format("You entered {0}",value)); } catch(System.Exception) { Console.WriteLine("Value is out of bounds"); }

231,172 PointsThe challenges can be rather picky about output strings. If you look closely at the "Bummer" message:
- ... I expected "Value is out of bounds!"
notice the exclamation point
- ... but got "Value is out of bounds"
For future questions, please ask a new question instead of adding a question as an answer to a different question. This will give you a better chance of a rapid response.

2,201 PointsHi Steven, thanks for this guidance. Is this applicable only to this particular code challenge, or is this a rule in general applicable to ALL situations, that the "throw" must be inside the try block?
