25th item in list has weird effect.

I have a page where people can order literature by filing a form. When they clcik submit it goes through the following PHP code:

<?php
$items = array(“Environmentally Sustainable Products”, “Green Circle Flyer”, “Green Action Initiative”, “Hurricane 670 XTT Spec Sheet”, “Hurricane 500 XTT Spec Sheet”, “Hurricane 600 XTT Spec Sheet”, “Professional Power Nozzles Spec Sheet”, “Propane High-Speed Burnisher Spec Sheet”, “Enviro Vac Spec Sheet”, “Blu-Lite Plus Feature Sheet”, “Film Away Feature Sheet”, “Power Lift Feature Sheet”, “Foundation Feature Sheet”, “Tradition Plus Feature Sheet”, “Soap Dispensers Spec Sheet”, “Eastern Chemical Price Book”, “Western Chemical Price Book”, “Equipment Agent Price Book”, “Equipment Distributor Price Book”, “Equipment SSP Price Book”, “MSDS Book”, “Parts Lists Book”, “Equipment Spec Sheet Booklet”, “Dustbane Catalogue”, “Info CD”, “Dustbane Sustainability Action Plan”, “Sanitation Programs”, “Since 1908 Presentation”, “WHMIS Overview”, “Dustbane Dilution Chart”, “Food Industry Wall Chart”, “Floor Care Chart”, “Carpet Care Chart”, “Washroom Care Chart”, “Hand Washing Chart”);
$values = array($enviro_products, $trifold, $green_action, $hurricane_670, $hurricane_500, $hurricane_600, $power_nozzles, $propane_burnisher, $envirovac, $blulite_plus, $film_away, $power_lift, $foundation, $tradition_plus, $soap_dispensers, $east_chem, $west_chem, $equip_agent, $equip_dist, $equip_ssp, $msds, $parts_lists, $equip_spec, $catalogue, $infoCD, $green_trends, $sanitation_programs, $since1908, $whmis, $dilution_chart, $food_chart, $floor_chart, $carpet_chart, $washroom_chart, $handwash_chart);

foreach($items as $key => $item)
if($values[$key] > 0)
$message .= $item . ‘: ‘ . ‘<b>’ . $values[$key] . ‘</b><br>’;
mail( “[email protected]“, “Literature Request – $name”, ‘<font face=”arial” size=”2″>’ . $message . ‘<p>’ . ‘<b>Note:</b><br>’ . $note . ‘<p>’ . $name, “From: $emailnContent-Type: text/html; charset=iso-8859-1” );
header( “Location: http://www.dustbane.ca/thanks_en.html” );
?>

It works for the most part, but I tested it ordering each and every item from that list and when I receive the request by email everything below item 24 (Dustbane Catalogues) is in bold.

I tried another test where I ordered 0 “MSDS Books” to see if everything below item 24 (Dustbane Catalogue becomes 23 since there are no MSDS Books, so the Info CD is 24 now). Everything below was NOT in bold, however, the 25th item is now “Dustbane Sustainability Action Plan” and for some reason, when I receive the email it is spelled “Dust! bane Sustainability Action Plan”.

What the heck is going on?
