C# C# Objects Inheritance Throwing Exceptions

Compiler showed me an error from a separate .cs file

Upon completing this objective I previewed it, and it showed me an error that referenced another file called Students.cs. This doesn't make sense...

Program.cs 
int value = int.Parse(Console.ReadLine());

if (value < 0 || value > 20)
{ 
    throw new System.Exceptioin;
}
else
{
    Console.WriteLine(string.Format("You entered {0}",value));    
}

I think you saw "Students‍Code‍.cs", which we can probably assume is part of the code "under the hood" that performs the challenge validation by including your "Program.cs". Unfortunately, it caused a confusing reference in the error message.

The "Unexpected symbol" part is still accurate, and the actual issue is that the name of the new exception was not followed by parentheses.

Also, you have "Exceptioin" (with an extra "i") instead of "Exception".
