Need some help with style sheet

I’m working on a site at http://clearly-organized.com/.
What I am having trouble with is this page:
http://clearly-organized.com/articles.html

I have two columns, and would like the text in the main column to wrap as soon as it hits the second column. As you can see on the page, it extends into the second column.

Can anyone give me a few pointers?
Although I’ve made some progress, Style Sheets continue to baffle me.

the reason it is going into the second column is because that string is larger than the space allowed. I bet if you use actual text it will wrap as expected. so instead of one long word use actual words to test and it will probably work for you.

Quite Right! Thanks!
