Hi Nancy!
One reason Google is saying that is because you have a large amount of links compared to the amount of regular text. That will make them suspicious.
You have ~100 links on the three subpages you´ve listed which is no problem, but, when it is compared to the amount of plain text this might happen.
See Matt Cutts blog post about this: http://www.mattcutts.com/blog/how-many-links-per-page/
