Good luck.

Hi Brett

   Thank you for responding.  I'm considering ordering new primers and
trying again...however...I'd like to be sure that I'm not barking up ther
wrong tree.  When you did the 9bp overlap, how long was your entire primer
(approximately, of course).  I'll try annealing at lower
temperatures...thanks again.
