What come in mind is sessions.

Sessions are stored on server and it goes something like this:

to set variables in session:

<?php
session_start();

$_SESSION['some_variable_name_1']='some_variable_value_1';
$_SESSION['some_variable_name_2']='some_variable_value_2';
...
$_SESSION['some_variable_name_n']='some_variable_value_n';
?>

to retrieve variables from session on other page:

<?php
session_start();

$some_variable_value_1 = $_SESSION['some_variable_name_1'];
$some_variable_value_2 = $_SESSION['some_variable_name_2'];
...
$some_variable_value_n = $_SESSION['some_variable_name_n'];
?>

But I would really encourage you to leave frames and tables and use css for element positioning - it is so much easier and you get more readable html.
