// BuildSyndicatePlaylist is the function to parse HTML forms and build the comma separated

//      This argument will be passed directly into LaunchSyndicateArticle
//	This argument is optional. If not passed in, the default video viewer template will be used

// BuildSyndicatePlaylist will parse the HTML on a page for all forms whose name attribute
// begins with the string 'ArticleList' (ie <form name="ArticleList_TopStories">).
// Within a matching FORM, the function will look for an array of checkboxes named V1.
// The value of a given checkbox should be the ID of the particular article.
// BuildSyndicatePlaylist will build a comma separated list of the values of all these checkboxes
// and pass that comma separated list into LaunchSyndicateArticle.
// If no matching forms or checkboxes are found, or if no boxes were checked,
// The function returns a message telling the user "You must select a story to add to your playlist!"

// <form name="ArticleList_TopStories">
// <input type="button" onclick="BuildSyndicatePlaylist();" value="Launch Your Playlist"><br>
// <a href="/" onClick="LaunchSyndicateArticle('23'); return false;">Watch Story #23</a>
