Help: lastIndexOf is not a function

[Mario Dorion]

Why is this causing me a "lastIndexOf is not a function" error:

var URL = top.location;
var idx = URl.lastIndexOf("somestring");

This one works, though:

var URL = "somestring";
var idx = URl.lastIndexOf("somestring");

It seems it fails to notice that the first URL is really a string.
Is there a way I can cast it?

Thanks in advance as my neck is on the line!

Variable names are case-sensitive. You change the case of the "L" from
URL to URl, which will throw off the lastIndexOf() method.

Still won't work. URL is a reference to an object, and can't be used directly with
string methods. It has to be:

var URL = top.location.href;

or

var URL = top.location.toString();

top.location is an object, perhaps you mean top.location.href

Perhaps you should go back to 1996, at which time your reply might have been more useful.
