  Yes, that is it! It works after I changed the 'html cancelButton' to 'html anchor'. Thanks, I never would have gotten that on my own. 

  I am a little confused about whether I nest html forms or not. I have so many different components with html form in them that I must be nesting forms. So, there should only one html form: for the entire page? Perhaps I can refactor my code to make that happen, although everything seems to work pretty well as it is written. What goes wrong when forms are nested?

  Regards, 

  Larry
