Hello, I doing this tutorial on JS book. I cannot figure out where in the beginning I am having errors. W3C does not validate JS and I am copying straight from the book and not getting it correct if someone can point out my errors, I will appreciate it. Trying to figure this out so I will know how to do the HW problem.

var returnValue;
var value1 = "First text string";
var value2 = "Second text string";

value1 == value2 ?
document.write("<p> value1 equal to value2: true <br />") :
document.write("<p> value1 equal to value2: false <br />");

value1 = 50;
value2 = 75;

returnValue = value1 == value2;
document.write("value1 equal to value2: " + returnValue + "<br />");

returnValue = value1 != value2;
document.write("value1 not equal to value2: " + retunValue + "<br />");

returnValue = value1 > value2;
document.write("value1 greater than value2: " + retunValue + "<br />");


returnValue = value1 < value2;
document.write("value1 less than value2: " + retunValue + "<br />");

returnValue = value1 >= value2;
document.write("value1 greater than or equal to value2: " + retunValue + "<br />");

returnValue = value1 <= value2;
document.write("value1 less than or equal to value2: " + retunValue + "<br />");


value1 = 25;
value2 = 25;

returnValue = value1 == value2;
document.write("value1 equal to value2 AND the same data type: " + returnValue + "<br />");

returnValue = value1 !== value2;
document.write("value1 not equal to value2 AND not the same data type: " + returnValue + "</p>");

I found it, I just copy and pasted it on Word and saw the problem, sorry for the post. But still are there JS validators(similar to W3C) and whats a good program for JS, kinda not liking Dreamweaver for this material.
