Thank you for the responses. I did have the nav bar moved to the front and the form is working fine. Actually, even the home button on the nav bar worked from the contact page.
Anyway, I figured out what was causing the problem (at least it works now). I had the pages set to transition instead of instant. When I changed them all back to instant, everything
worked fine. Wasn't sold on the transition effect anyway, so wasn't a big deal to lose it.
