Sorry - I know that I am making this complicated but I don't know how else to do it. I'm looking at if/else, switches, try/catch.
Thanks in advance,

And as Edward pointed out, there's a missing variable in the conditional expression. The conditional should control the throwing of the exception.

Typo on catch. Try looking up how to use the catch statement. It needs some work, but I'm thinking your main problem is the comparison.

Courses Plus Student 629 PointsRight! Thanks - will give it a go tomorrow. Cheers.

Here is how I solved it using an if statement:
int value = int.Parse(Console.ReadLine());
if (value < 0 || value > 20)
{
throw new System.Exception();
}
Console.WriteLine(string.Format("You entered {0}",value));
