so.. im tryign to paginate a div with content being added by an input. but its not working at all...

first, I got this input:

Code:
<form name="postbar_add_post" id="postbar_add_post"  method="post">
	<fieldset>
    	<legend>What chu doign? ...</legend>
        <input type="text" name="addcontentbox" id="addcontentbox" maxlength="200" />
        <input type="submit" name="addpost" value="Submit" class="submit" />
      	</fieldset>
</form>
then, what i will happen is that, the content being submited, will be posted to an unsorted list, named wall, i used jquery to help me out on this, heres the script:

Code:
<script type="text/javascript">
$(document).ready(function(){
	$("form#postbar_add_post").submit(function() {
		var addcontentbox = $('#addcontentbox').attr('value');
		
		if ( addcontentbox.replace(/\s/g,"") == "" ) return false;
		
$.ajax({
type: "POST",
url: "postear.php",
data:"addcontentbox="+ addcontentbox,
success: function(){
$("ul#wall").prepend("<li>"+addcontentbox+"</li>");
$("ul#wall li:first").fadeIn();
document.postbar_add_post.addcontentbox.value='';
document.postbar_add_post.addcontentbox.focus();
}
});
return false; 
});
});
</script>
the div where it is beign opsted at, looks like this:

Code:
<div id="cuerpo"><ul id="wall"></ul></div>

adn then, below i got this div, wich is where the navgiation links will be at:
(before u read, "current_page" and "show_per_page" are 2 hidden inputes to save the values.)

Code:
<div id="navwrapper"></div>
so, to make the navigation, i found a script online and tried to adapt it to the div, i got this:

Code:
$(document).ready(function(){ 

	//how much items per page to show  
	var show_per_page = 5;  
	//getting the amount of elements inside content div .   
    var number_of_items = $('#wall').children().size();  
    //calculate the number of pages we are going to have  
    var number_of_pages = Math.ceil(number_of_items/show_per_page); 
	
	//set the value of our hidden input fields  
    $('#current_page').val(0);  
    $('#show_per_page').val(show_per_page);  
	
	
	//navigation '  
  
      
    var navigation_html = '<a class="previous_link" href="javascript:previous();">Prev</a>';  
    var current_link = 0;  
    while(number_of_pages > current_link){  
        navigation_html += '<a class="page_link" href="javascript:go_to_page(' + current_link +')" longdesc="' + current_link +'">'+ (current_link + 1) +'</a>';  
        current_link++;  
    }  
    navigation_html += '<a class="next_link" href="javascript:next();">Next</a>';  
  
    $('#navwrapper').html(navigation_html);  
  
    //add active_page class to the first page link  
    $('#navwrapper .page_link:first').addClass('active_page');  
  
    //hide all the elements inside content div  
    $('#wall').children().css('display', 'none');  
  
    //and show the first n (show_per_page) elements  
    $('#wall').children().slice(0, show_per_page).css('display', 'block');  
  
});  

function previous(){  
  
    new_page = parseInt($('#current_page').val()) - 1;  
    //if there is an item before the current active link run the function  
    if($('.active_page').prev('.page_link').length==true){  
        go_to_page(new_page);  
    }    
}  

function next(){  
    new_page = parseInt($('#current_page').val()) + 1;  
    //if there is an item after the current active link run the function  
    if($('.active_page').next('.page_link').length==true){  
        go_to_page(new_page);  
    }  
} 

function go_to_page(page_num){  
    //get the number of items shown per page  
    var show_per_page = parseInt($('#show_per_page').val());  
  
    //get the element number where to start the slice from  
    start_from = page_num * show_per_page;  
  
    //get the element number where to end the slice  
    end_on = start_from + show_per_page;  
  
    //hide all children elements of content div, get specific items and show them  
    $('#wall').children().css('display', 'none').slice(start_from, end_on).css('display', 'block');  
  
    /*get the page link that has longdesc attribute of the current page and add active_page class to it 
    and remove that class from previously active page link*/  
    $('.page_link[longdesc=' + page_num +']').addClass('active_page').siblings('.active_page').removeClass('active_page');  
  
    //update the current page input field  
    $('#current_page').val(page_num);  
}


but all looks cool but... it is actually not working... everything its being posted great to the unsorted listt, but its not paging =S. .. it just all shows on the div, and scrolls.

Could it be somethign on the css? ... or... what ...? =|


Guidance? =( . my brains toasted. =\
