Javascript Form Calculation Error :banghead:

I need help. I have a form that gives a running total, however, the calculation isn't coming up properly. Any help would be appreciated. I am new to this forum, so if I haven't posted correctly, please let me know.

I attached a notepad file to this post, so if it can't be read, I can post it in here.
Thanks.
