Post hidden content in a form

HI,

I followed the "list and detail pages" to set up an area on the website where users can book onto training sessions.

I currently have...

• multiple course pages, each listing x3 regional options
• Once a user has clicked on a regional option it shows the detail - along with the option to book a place

When a user clicks book now I want it to go to a booking page showing the course title and regional detail, along with a form for the user to input details.

Where I'm stuck at

I managed to pull the course title and regional detail into the booking page as a summary, but

I cant figure out how to submit the course title and regional detail through the form, I've tired hidden fields using the ID's I set but it just return blank on submission.

This is how i have pulled the details content onto the booking page

    $sql = "SELECT pci.indexKey, pci.indexValue, pp.pageTitle
     FROM perch2_content_index pci, perch2_pages pp
     WHERE pci.pageID = pp.pageID
     AND pci.itemID = ".$DB->pdb($_GET['id'])."
     GROUP BY pci.indexKey
     ORDER BY pci.indexID DESC";
     $rows = $DB->get_rows($sql);

     // Assign variables to each array value

     foreach ($rows AS $value) {
        $formVars[$value['indexKey']] = $value['indexValue'];
        $formVars['pageTitle'] = $value['pageTitle'];
     }
     echo '<div class="small-12 columns"><h3>' . $formVars['pageTitle'] . ':</h3></div><hr />';

     echo '<ul class="small-block-grid-2">';
     echo '<li><b>Region:</b> ' . $formVars['region'] . '</li>';

     .........

Any guidance would be a massive help
