$_POST data not mapping to $this->input->post

[eluser]randalrust[/eluser]
I am completely new to actually coding with CI and MVC, but have a lot of experience with OOP in PHP. I am working through a tutorial [1][2], but I'm having an issue that I don't quite understand.

My form_view has the following fields:

first name
last name
seminar (four checkboxes)
comments (textarea)

When I properly fill out and submit the form and the data is passed to the controller, I keep getting error messages that say:

A PHP Error was encountered
Severity: Notice
Message: Undefined index: email

The exception is the 'seminar' field. If I check a box, then it works properly.

I know the data is getting passed, because I can echo the $_POST array and see it.

Oddly enough, I added this to my controller file:

$this->input->post['fname']=$_POST['fname'];
$fname=$this->input->post['fname'];

Then I was able to avoid the error on the 'first name' field. So what it looks like is that the $_POST array is not getting properly passed to $this->input->post. Any thoughts?
