Problem #4:
JavaScript Errors - You decided to add JavaScript to your page but you're getting an error.Solutions:
1. Check each line in your script to make sure you didn't miss anything. If you made any changes to the script, check to make sure you added the tags right.
2. Make sure you put your script in the right place. Some scripts are put in the body of your page and others are meant to be put inside the <head> tags.
3. Use already made scripts from a JavaScript site.
