Removing line under product listings

[Harvard]

I've been looking at stylesheets for the last hour and can't find out where the line under the product listing is located.
MY site is: http://bootscouture.com
As you can see there is a sold gray line as well as a dotted line. I need the solid one removed.

Any help is appreciated :)

Find this in stylesheet_tm.css and remove the border-bottom:

.product_list_col {padding:8px 0; border-bottom:1px solid #E3E3E3;}

This stuff is easy to locate using the Web Developer plugin for the Firefox browser - very handy tool.

Awesome, that fixed it. Downloading that tool now too!
