Trouble with redirect after wav file is saved

Okay I appreciate you hanging in here with me!  So I moved things around like you mentioned and was able to get rid of the error messages.  When I ran it again it creates my wav file but doesn't redirect to the thank you page.  The following is my complete AS File...  maybe I missed something that you suggested...
