Rick, I understand where you're coming from. Years ago I really struggled with learning Javascript. I hated it and really resisted it, but realized that it is an inescapably valuable toolset for a web developer. So I perservered and now I'm pretty good at it. Books that I recommend include Visual Quickstart Guide titled "JavaScript For The World Wide Web" by Tom Netrino and Dori Smith. It's a "cookbook" style of book that makes it very easy to learn as you go. I also highly recommend the "Javascript Bible" to use as a reference. Another invaluable tool is to use the Javascript console in FireFox to help you in debugging your code.
HTH.
