  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Hi Walter, I don't know what you were doing wrong cause I didn't see your answer. But this worked for me.

var a = 10;
var b = 20;
var c = 30;
if(a > b){
  alert("a is greater than b");
}else{
  alert('a is not greater than b');
}

ok found it

var a = 10;
var b = 20;
var c = 30;

//<=== is not a comparison operator in JS...I don't think.
if ( answer <=== '20') { //also "answer" is not part of the comparison
  alert('a is greater than b'); //we are only comparing a and b
} else {
 alert('a is not greater than b'); 
}

This is great! Now, I understand...I was having trouble understanding the Task I found myself reading it a couple of times and somehow, it still didn't make sense to me.

Thank you very much John! Happy coding!!!

Hello, what exactly are you trying to do? I took a look at the code in you workspace (which is different from the one you posted) and the first thing I noticed was that you <script> tag importing your js script is out of place. It's not that it won't work, it's just that you don't usually import a script in the middle of your HTML code. It is good practice to not mix the two, so you should do your <script src="quiz.js"></script> either in the <head> or at the beginning or end of <body>, try no to put them in the middle of the html components.

Also, in your code you define variables a, b and c, and then you try to compare "answer" with one of the variables. Of course, this "answer" is not defined, so the result of your code won't be what you expect. Were you maybe trying to compare a with b?

Also, the comparison you are trying to make is not correct. Instead of <===, you should actually use <=.

Moreover, you first define your variables a, b and c as integers, but then you try to compare them with a string. I believe you are trying to do, for example, if (a <= 20) and not if (a <=== '20').

As you can see, there are a lot of issues with your code. Can you tell us what you are trying to achieve?
