Problems With Setting up Portfolio Using PHP

I’m in the beginning stages of creating a portfolio website and I’m completely stuck. I’ve uploaded the site here: http://www.gregoryrich.com/blog. I don’t know a lot (barely anything) about PHP, and I used an online tutorial (http://wp.tutsplus.com/tutorials/widgets/using-custom-post-types-to-create-a-killer-portfolio/) to create the portfolio items.

I successfully set up the Portfolio function on my dashboard and everything seems to be working fine, however tonight I noticed that the links in my portfolio items are not working. They’re displaying, but it seems as though they have no target. They were working properly before, and I cannot understand where the problem is occurring.

Any help or suggestions would be greatly appreciated!
