The panic attack forms are so you can write out what you are feeling at the moment. Fill them out every time you get a panic attack. Fill out your diary every day also. The computer diary is so you can look back and see your progress. I know it seems redundant but you'll see that it really does help to get it all out. One thing I have seen is that you can't get back into the diary entries on the computer. It just shows you a graph of how your panic levels were each day throughout the month. So, the paper forms really help if you want to look back and see what you were feeling and how you reacted at that point compared to how you react to situations now.
What I do is use the paper forms at the moment and then update the diary every night with what I had written on the forms. It seems like a lot of work, but you'll be surprised how much it helps.
