Answer 1

Document.all doesn't work in Firefox, you need to use document.getElementById().<br />
See https://developer.mozilla.org/En/DOM/document.getElementById
<pre><nowiki> var parseYear = parseInt(document.all.year [document.all.year.selectedIndex].text);
var newCal = new Date(parseYear , document.all.month.selectedIndex, 1);
</nowiki></pre>
