line 10 you have:
$rsLists->setQuery("SELECT DISTINCT FullName, CountType, CountArea, FullName, CONCAT(CountType, " - ", CountArea) AS CountDef FROM birdlists WHERE FullName=? ORDER BY CountType, CountArea");
it should be:
$rsLists->setQuery("SELECT DISTINCT FullName, CountType, CountArea, FullName, CONCAT(CountType, ' - ', CountArea) AS CountDef FROM birdlists WHERE FullName=? ORDER BY CountType, CountArea");
To get the full error you can open up rsobj.php and turn on debug mode.... where it says ->Debug = false; on the top of the page, change it to "true".
