PHP - Form Passing Incorrect Values.

i am writing this script for use as an include in joomla and the directphp plugin so in my joomla article i have:
Code: [Select]
<?php
include 'test/conducttest.php';
conducttest();
?>
Ok now my issue!
the form in this function is passing only the values for the last item in the loop rather than for the selected radio item when submitted.
so when say for example the radio selected is:
ID TEST TYPE UNIQUE TEST ID AVAILABLE 5    Adolescent Clinical 50021629 1
and the last item in the list is:
ID TEST TYPE UNIQUE TEST ID AVAILABLE 4 Adult Clinical 12341629 1
When the form is submitted even if the 1st item is selected, it returns the value for the second one. I am sorta new to php so any suggestions will be appreciated.
Here is my full code:
Code: [Select]
<?php
function conducttest() {
    //GET JOOMLA USER ID & USERNAME FOR LOGGED USER
    $user =& JFactory::getUser();
    $userID = $user->id;
    
    //GET JOOMLA DATABASE OBJECTS
    $db =& JFactory::getDBO();
    
    //NEW TESTS QUERY (what purchased test are available for use with 'item_available' == '1' {unused test} and matching current 'user_id')
    $new_query =    "
                SELECT *
                FROM crt_transactionHistory
                WHERE user_id = ".$userID." AND item_available = '1'
                ORDER BY item_name, id
                ";
    $db->setQuery($new_query);
    $new = $db->loadAssocList();
    
    //OPEN TESTS QUERY (what purchased test are available for use with 'item_available' == '2' {resume test} and matching current 'user_id')

                ";
    $db->setQuery($resume_query);
    $resume = $db->loadAssocList();
    
        //DISPLAY use_test FORM
        if(!isset($_POST['test'])) {
