Installing Fancybox

I have installed fancybox module and included updated Fancybox Version: 1.3.4 (2010/11/11) from fancybox.net I have copied this code to fire up the plugin into Jquery selector window.

$(document).ready(function() {

$("a[href$=.jpg],a[href$=.png],a[href$=.gif]").fancybox();

});

However after I save configurations i receive this message.

Notice: Undefined index: options in _save_fancybox_settings() (line 187 of /home/content/08/7320308/html/modules/fancybox/fancybox.admin.inc).
Notice: Undefined index: padding in _save_fancybox_settings() (line 187 of /home/content/08/7320308/html/modules/fancybox/fancybox.admin.inc).

Notice: Undefined index: changeSpeed in _save_fancybox_settings() (line 192 of /home/content/08/7320308/html/modules/fancybox/fancybox.admin.inc).

After I go in and change the values and test out the fancybox however it does not work. nothing happens.
Please help. Tried everything possible.
