I had no need to change prices based on attributes, so I didn't notice the problem until I tried to see if I had the error. I tried to add prices, but it didn't work. Per advice, I installed 2.1b and price attributes worked.
I have STS and Ultra Pics installed. If anyone else is having the same problem, try the 2.1b package as it seems to do everything it should and works for many people.
Even with these minor problems, this contribution has saved me many headaches and enough time to warrant any additional steps I've needed to take to get it working. Do not let a few minor problems deter you from adding this awesome contribution.
Thanks.
