3 php scripts are involved...
1.php = contains an html form that prompts user for inputs (method get). Those inputs are stored in a session variable and by virtue of the form action script 2.php is called.
2.php = produces an html table based on the user inputs from 1.php via session variables. A submit button is used to allow user to access script 3.php.
3.php = produces another html table and the 1.php user inputs are needed to be successful.
1.php works as intended and so does 2.php however, in 3.php the session variables are blank.
