use

margin: auto auto;
don't use

margin-right: auto;
margin-right: auto;
and don't forget

body {

indeed, it won't work with absolute positioning

align=center doesn't work on divs.
try this:


body {
text-align: center;
}
.style1 {
margin: auto auto;
}

Could you post a dummy html page with all your css and javascript in it? Then it will be a lot easier to get some answers I guess :)

try putting it in the form's onsubmit event, like this:

<form onsubmit="return validate_form()">

this should work:

object.style.display = "block";
object.style.display = "none";

"hidden" doesn't work on .display, only on .visibility

What about Aptana (http://www.aptana.com)?

Could you post the corresponding HTML code?

Try this:

var xmlDoc;
if (window.ActiveXObject)
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
else if (document.implementation && document.implementation.createDocument)
xmlDoc=...
