    I solved the problem and posted it on another blog.  I think the key is to put the actions into the WSS.Actions file.  After doing this I was able to see the helper functions.  All of the examples he has listed above work.  The problem is that I can’t figure out how to use WorkFlow variables with the helper functions.  I tried to substring one of my date values and then display the chopped date value in an email.  This does not work at all because the program treates the variable as a string i.e. "[%_x005f_string47%]".  I doubt that these helper functions work with WorkFlow variables at all.  I ask how is this useful if I can’t use WorkFlow variables?
     
    Perhaps I am missing something?

      Hi, Manoj. I assume you figured this out a long time ago. Sorry for not replying back in 2010 when you made the comment.
