passing variables from one form to another

Hi, I have a PHP script (script_one.php) that creates a small form containing a table of links. In my script I declare an array, $myarray[$total_links], of the same size as the number of links. Each link is coded as such: <a href="../phpscript/script_two.php?myvar=' . $myarray[$i] . '&element=' . $i . '"> This way, I pass the both the value of my array at elemnt "i" and which element I am accessing to my second script. This second script opens a new window and creates another small form with an input field. I allow the user to enter information into an text field and close the window. Question: How do I pass the results of that information back to my original script and stuff it into the array at the element chosen? Thanks, Don
