getting an error "Unexpected symbol `System' "

I've been staring at my code for longer than i'd like to admit trying to figure out what is wrong. for some reason it looks like it doesn't like my using statement. any advice?

CodeChallenge.cs 
using System;
string input = Console.ReadLine();
int temperature = int.Parse(input);

    if(temperature < 21){
         Consol.Writeline("Too cold!");
    }
    else if (temperature >= 21 ||temperature <= 22 )
    {
       Consol.WriteLine("Just right.");
    }
    else 
    {
       Console.WriteLine("Too hot!");
    }

Hi there! First, and foremost, the reason that you're getting that error is because they've included the System for you. But, even if we remove the first line there your code will still fail. Your first WriteLine is misspelled. You have "Writeline" instead. The first two Console are misspelled. After changing those, you still have a logic flaw. If I were to send in the temperature of 90 right now, your code will print out "Just right". The second else if says that if the temperature is greater than or equal to 21 or less than or equal to 22 print out "Just right". 90 is greater than or equal to 21. Remember, if we use OR only one has to be true for the code to run. Try again with these tips in mind! Happy coding! :sparkles:
