RE: Having Problems with JavaScript

Justin,

Not to ask really dumb questions, but this is inside a properly formatted
HTML document, right?  What's confusing me is that the line number of the
error is "0", and I'm not really sure how that can happen.

When there is an object expected error it usually means that it couldn't
find a variable in the JS or the DOM element (like a form or form field).

I don't see a glaring problem right off, but what if document.cookie doesn't
exist, would this still work?

Here is an example of my cookie routine which only runs if the cookie
exists...

<script language="JavaScript">
<!--
function getCookie(the_info)
{
if (document.cookie){
var the_cookie = document.cookie;
var the_cookie = unescape(the_cookie);
var broken_cookie = the_cookie.split("=");
var the_values = broken_cookie[1];
var separated_values = the_values.split("/");
var property_value = "";

for(loop = 0; loop < separated_values.length; loop++)
{
property_value = separated_values[loop];
var broken_info =
property_value.split(":");
var the_property = broken_info[0];
var the_value = broken_info[1];
the_info[the_property] = the_value;
}

// do stuff

var cookie_information = new Array();
getCookie(cookie_information);
//-->
</script>
