Passing SESSION variables
<p>Let's say I have a questionnaire consisting of three pages that a user is supposed to submit.
I collect variables through SESSION.
Should I pass all the variables in session from page to page repeating them or could I pass variables from page one to page three? 
For example, I have 'first name' and 'last name' on page 1, 'email' and 'address' on page 2, 'age' and 'occupation' on page 3.
Could I pass 'first name' and 'last name' from page 1 directly to page 3?
Or I will have to pass them to page 2 first and then pass them again from page 2 to page 3?</p>

<p>Thank you!</p>
