Hi Donna,
I took a look at this template and I think the problem is it has no column layout, it is all just one center column so the Artisteer CSS has nothing for side columns. I would change it to have 2 column layout in Artisteer then export it and it will have the ingredients needed to support column layout and this is needed since mojoPortal adapts from 1 to 3 columns.
Once you add a column to the template export it again and use the artisteer-swirly1 skin as the starting point.
Hope it helps,
Joe
