PHP PDO Update function silently fails

Question

I'm at best a hobbyist who is just now bringing to use PDO and i'm have a heck of a time with insert statements. I have a function which is meant to update several columns in a table but my data does not seem to be binding correctly? I've looked over google, php.net, http://wiki.hashphp.org, stack overflow itself, and the sql site, but i've not found a solid example i can draw an apples to apples comparison too on how to do this. I've seen lots of examples where they update a single column, but none showing how to update a couple columns and i'm just not able to figure it out.

hopefully someone out there can help me and my flu soaked brain figure this out.

MY FUNCTION:

function timelineRevise(){
#TimelineID & EntryID passed as hidden post values from timelineEdit() function
/*
     <input type="hidden" name="EntryID" value="' . dbOut($row['TimelineID']) . '" />
    <input type="hidden" name="EntryID" value="' . dbOut($row['EntryID']) . '" />
*/
$TimelineID     = strip_tags($_POST['TimelineID']);    #int - primaryKey
$EntryID            = strip_tags($_POST['EntryID']);           #int
$EntryTitle     = strip_tags($_POST['EntryTitle']);        #str
$EntryDate          = strip_tags($_POST['EntryDate']);         #str - entered by user
$EntryDescription   = strip_tags($_POST['EntryDescription']); #str
$CharTag            = strip_tags($_POST['CharTag']);          #str of comma sep numbers


$db = pdo(); # pdo() creates and returns a PDO object

//dumpDie($FirstName);

$sql = "
    UPDATE ma_Timeline

    SET
    TimelineID              = :timeline_id, #PrimeKey

    CharTag                 = :char_tag

    WHERE EntryID           = :entry_id";

$stmt = $db->prepare($sql);

//The Primary Key of the row that we want to update.
$stmt->bindValue(':timeline_id',  $TimelineID,              PDO::PARAM_STR); #INT - PrimeKey
