Thank you Steven for all of your help! After a few hours of closely looking through all of the code, I remembered that I had created a div for a background with a width of 100% to go across the entire page (not just the columns). I think that the Juicebox was taking that width instead of the column that it was in.
I also had to play around with the juicebox container's width... and it somehow worked!
Thanks again for your patience!
