I obtained an author's widget from: *************.com, ******.com, ******.com each.
They are all in Javascript.

When placed in Sidebars, the W3C validator raises a hundred errors. However, when placed in a Page, it works flawlessly.

I tried many forums. Till date no one has given any reason why it happens. Can anyone help me out?

The widget code is like this:

<script type="text/javascript" src="http://*************.com/widget/inc/eawidget.js"></script><script type="text/javascript" src="http://*************.com/widget/widgetfetch.php?theme=100&cheader=bb2020&cborder=d0d0d0&cbackground=f1f1f1&ctopic=f1f1f1&ctopictext= 000000&ch3=bb2020&cfooter=f1f1f1&cfootertext=000000&mem=805036&height=400&width=270&articles=10&auth orid=My Name&bio=1"></script>
