That's great! May I ask which comma it is?
A lot of people report that their iWeb created website but also non iWeb created websites don't display correctly in IE. It is just a code however all browsers have to read that code, understand it and render the code (display to you what the code means=>ex. slideshow).
Codes are languages (there's HTML, Javascript, CSS, PHP, ...). Browsers are people (Safari, Firefox, Chrome, IE). I could answer your question in Italian or German or French or English (code languages). You may understand or not understand the answer depending on whether you speak these languages or not. Or in my answer I could use a word like
lobectomy and you may know what it means or may not know what it means. Hence you would get the answer or not. Internet Explorer doesn't understand Javascript very well, it may know the basics (What's your name? Come ti chiami? What's your job? Cosa lavori?) but it can't manage a real conversation.
Different people talk different languages. They may know some languages better than other. Same for the browsers. Some do a better job on some languages (codes) others at other.
