Pinboard issues

Using the Pinboard theme, on the Layout Tab under Theme Options, I have the first theme layout selected (larger left content column and smaller right sidebar column). I have 2 columns listed under Content Columns (one for content and one for sidebar). After saving the theme options, when I view the website it appears as 50% content column and 50% sidebar column. On my Ordering page, I have selected the No Sidebars template, but the sidebars still show up. I don’t necessarily mind having the sidebar visible on the Ordering page, but need it to be 1/4 the size of the whole page, with the content being 3/4 the size of the whole page.

Any help would be appreciated as we would like to have the page ready for a fundraiser that we are participating in on 11/02/13.

Thank you!
