I am trying to add the ad module.

[Zachery]

On what page? And what does your ad code look like?

[sudbury8]

The errors is happening on home pages when try to add a mod .The only one I have been adding at this time is the ad mod.I am putting it on the right side of the pages and I am inserting the code below in it ,one ad mod per page.
<script type="text/javascript">
( function() {
if (window.CHITIKA === undefined) { win.I dow.CHITIKA = { 'units' : [] }; };
var unit = {"publisher":"johny2000","width":300,"height":250,"sid":"Chitika Default","color_site_link":"0000CC","color_bg":"FFFFFF"};
var placement_id = window.CHITIKA.units.length;
window.CHITIKA.units.push(unit);
document.write('<div id="chitikaAdBlock-' + placement_id + '"></div>');
var s = document.createElement('script');
s.type = 'text/javascript';
s.src = '//cdn.chitika.net/getads.js';
try { document.getElementsByTagName('head')[0].appendChild(s); } catch(e) { document.write(s.outerHTML); }
}());
</script>
