Form Validation, validation->error_string not displaying

[eluser]freakish777[/eluser]
So following the instructions here, when I don't fill out the form correctly I don't see the error string above my re-loaded form. However when I switch:

Code:

if ($this->validation->run() == FALSE)
{
   $this->load->view('myForm');
}

to:

Code:

if ($this->validation->run() == FALSE)
{
   echo $this->validation->error_string;
}

I do in fact see the error string.

Has anyone else experienced something similar? Is there some type of scope issue on the variables? I would imagine once they're set they'd be accessible in any of the views you load them in later...
