I'm sorry to spam the list like this, but I really need help on this. Igor's
solution doesn't seem to change anything. No information is transferred to
the database upon hitting "on submit". If no one knows the solution, does
anyone have any ideas on how I could debug this? Is there some way I can
reference the selections of the radiogroups from the the onSubmit method so
I can see what their values are?
Thanks for any help you can give,
Alex
