Running your code the HTML in
$article (cut down) looks like
<form
action=""
id="raaga"
method="get"
name="raaga"
onsubmit="return validate(this);"
>
<table
align="center"
border="0"
cellpadding="1"
cellspacing="2"
height="100%"
width="100%"
>
<tr>
<!-- snipped -->
</tr>
</table>
</form>
There is one table but it doesn't have an id attribute. It has a width attribute of 100%.
So your
my $table = $article->look_down(_tag=>'table',class=>'dataTbl',width=>
+"450");
won't find anything (
$table will be undef).
There is a lot of javascript. When I point Firefox at that url the response does not contain a form with an id of raaga. What does the page look like when you log in?
Give a bit more detail on what you are trying to do.
