Ads Not Appearing on Blog

Hi Sakin, I've been able to place ad boxes on the "homepage", but when I try to place a 2nd group of ad boxes on the archive blog page, it doesn't do it. I've tried placing the WP 125x125 on the main menu, blog posts page and a secondary area. But doesn't happen. I would like to place ads in the posts pages. Any suggestions? I am using WP 125x125 plugin. Site is www.iwritegreatcopy.com. Thanks for assistance. - Karin
