Repeat Column change for Categories

Hi All

I'm trying to find the right place to change the repeat column change for displaying products after clicking on a Category in the left nav area. Right now I've got one product per line, I'd like 3.

I'm guessing its a Category or Product ascx file somewhere, just can't locate it.

Thanks

Ok, found it. Just choose a template in Categories of Products In Grid and then change the template repeatColumns to whatever...
