You didn't define it

Code: 
// The weight of the egg [!](there should be a carriage return here)[/!]weight = window.prompt('Please enter the weight of the egg in grams','');
document.write('The weight of the egg is ' + weight + ' g.');// Confirming the input //


Just so you know, you're not supposed to post homework in the forums. Next time you have a question like this go ask your teacher.

You're going to need some more help with the programming because there are several other errors in the code that will prevent it from working.

The first clue that you are a newbie is that you confused JavaScript with Java. That is like confusing Pascal with Fortan.

f1girl2, when you downloaded this assignment you should have read a warning about submitting work that was not your own. Tutors can read these forums too!

You've somehow managed to lose a carriage return from the supplied file. However, there are more serious things wrong than that. You need to understand what it means to enclose part of the text in quotes, for example. There's really no substitute for working step by step through the course material, doing ALL the exercises. That way you soon discover you haven't understood something, and you can go back and have another look.

If you're really stuck, the person to ask is your tutor - or you could try your regional M150 conference.

I see that you know very little about JavaScript.
Don't make it more complicated than it is..
Basicly this is how it could be done:

Code: 
var egg_w = window.prompt('Please enter the weight of the egg in grams','');
   if (egg_w && parseInt(egg_w)) {
   egg_w = parseInt(egg_w);
   document.write('The weight of the egg is '+egg_w+'g.<br>');
      if(egg_w < 53) {document.write('It is a Small egg.<br>');}
      else if (egg_w < 63) {document.write('It is a Medium egg.<br>');}
      else if (egg_w < 73) {document.write('It is a Large egg.<br>');}
      else {document.write('It is a Very large egg.<br>');}
   }
   else {document.write('You didn\'t enter the weight!');}
document.write('Thank you for using this program.');

This would output (if weight is defined correctly by user):

The weight of the egg is ##g.
It is a Xxx egg.
Thank you for using this program.
