Portfolio/Assignment Validation

Ok this is a double barrel question so hope the subject doesn't confuse it...
firstly I want to find out if the assignment is all the questions in Tut101
or only the questions with the heading Assignment (so inversely not the ones with the heading Portfolio page)

ok just before I ask about the validation question...
before the assignment/portfolio section there is a sentence that say's
"All your code for a specific task should be on a single page.....do not pass data from one page to another...."

ok so the validation question states.. "if data is missing, the form is presented again."

my question... what if the data is correct and nothing is missing?
do we just clear the fields...?

sorry might have the answer... do we follow the welcome screen example route..where we echo the data but the form is no longer seen?

Yes, the assignment only requires us to code four links. The portfolio can only be done after you do the assignment.

Even If the data is missing, why use another page let all ur code run from one page

Correct r.e. links.

It must keep showing what is correct with no need to retype.

Let me try and see how far this takes me but thus far I think I am on track with the assignment
