passing variables

[eluser]briggl[/eluser]
Thanks, JonyR

I got it to work by using

$data['username'] = set_value('username')
$data['email'] = set_value('email')

But now I have a follow-on question.

By doing this I can pass the information to the next view, formsuccess.
How do I create a global variable so that I can pass the information on to other views after that?
Thanks.
