Characteristics names unchanged when switching

I just installed this component and I am having some difficulty. I have two products published, each with 9 color options. I have identical settings for each product. On the GSR3 product, when you select a color option from the dropdown, it changes the title to the correct color option. On the GSR5 product, it doesn't change at all. This is in Firefox.
In IE, neither changes the title. What's even more strange is if I change the default characteristic in the GSR3 to the first option, it makes it stop changing as well?
I am using the RocketTheme Quantive template. The site is at midsouthtechnologies.com/georgia_sr . Any help would be greatly appreciated!
