the title sums it up....

I'VE DONE
-----------------------------------------------------------------
searched the forum, didn't find anything to solve my problem and with google this seems to be a symptom for many problems, no luck there either.

there isn't really any component i can play with to troublshoot, it's syntax related.

MY SETUP:
--------------------------------------------------
I'm using javascript and reading an XML document. using a for loop, i display all the nodes in the XML and print to the page.

MY PROBLEM:
-----------------------------------------------------------------
i get the following annoying error after page load:
Line: 239
Char: 5
Error: "Object Required"
Code: 0
URL: www.blah.com


i've pasted the related code.

line "239", the error is indicated.


novice web programmer, greatly appreciate any pointers, directions, tips, tricks, workarounds etc.

var titleArray = new Array();
for (var x = 0; x < 20; x++) {
var TEXT;
if(TEXT=news.childNodes.item(x).firstChild.data){
if (TEXT.nodeType == 1){
titleArray.push(TEXT);
}
}

You may be grabbing white space or another <tag>, not text nodes. And
hard coding the loop max can be a problem too, unless you know there are
exactly 20.
for (var x = 0; x <news.childNodes.length ; x++)

SIMPLIFIED QUESTION:
------------------------------------------------------------------

in short, why is this illegal?

var titleArray = new Array();
for (var x = 0; x < 20; x++) {
//BELOW IS LINE 239, THE ERROR****************
titleArray = news.childNodes(x).firstChild.text;
}

because i commented out everything but those lines, and still got the same error.
