I have been trying to manipulate the code to adjust how the listing grid is displayed but no luck. I am trying to create a sort of cascade similar to the escort template. I want the listing grid to display up to 3 columns of listings (3 horizontally across)

I found part of it at:
div#listings div.item and was able to reduce that area.
I could not figure out how to edit the 'TD' it sits in to show 3 across instead of 2.


Can someone please illustrate to me the correct way to go about this?
