Jquery plugin problem

Jquery plugin problem

Hi there, I'm using a jquery plugin, but when I use it twice, it won't work. More than 4 hours between stackoverflow, jquery : how to create your own plugin..., to comprehend the $.fn, but no result this is the plugin source:
and this is
my usage:
first call is allright

var target='../ajaxScrollFav.php';
$('#favRes').scrollPagination({

nop     : 5, 
offset  : 0,
error   : '<div class="alert  alert-info"><center>Il n\'ya pas  des données.</center></div>'

  , 
delay   : 500, 
scroll  : true, 
target:target

});
});

and this is the second call
var target='../ajaxUtilScrollRes.php';
$('#content').scrollPagination({

nop     : 5, // The number of posts per scroll to be loaded
offset  : 0, // Initial offset, begins at 0 in this case
error   : '<div class="alert  alert-info"><center>Il n\'ya pas  des données.</center></div>'

  , // When the user reaches the end this is the message that is
                           // displayed. You can change this if you want.
delay   : 500, // When you scroll down the posts will load after a delayed amount of time.
              // This is mainly for usability concerns. You can alter this as you see fit
scroll  : true, // The main bit, if set to false posts will not load as the user scrolls. 
              // but will still load if the user clicks.
target:target

});
