Unindent the 'return render_to_response(...' lines, so that they are
executed when you have an invalid form. The form will be re-rendered,
except this time the form instance will be bound, and have appropriate
error messages in it.
eg:
if request.method == 'POST':
form = ...
if form.is_valid():
...
else:
form = ...
return render_to_response(...)
