Help, paging in single-CUSTOMTYPE.php ?

hi, im trying to figure out how to make the paging work in single-customtypename.php

Im using this code, it works when i use it on page templates but when it is in single-videos.php doesnt work.

BTW, my php level is medium-low.

i successfully get the related custom type based on the category of the current post. However when i go to /page/2/ i get 404 error. I have refresh my permalinks several times, that doesnt seem to be the problem

global $paged;

$paged = get_query_var('paged')? get_query_var('paged') : 1 ;

$temp = $wp_query;
$wp_query = null;
$wp_query = new WP_Query();

$wp_query->query(array(

'post_type'        => 'videos',
'posts_per_page'=> '4',
'paged'            => $paged,
'categoriesvideos'	=> $term->name,  

));

How do you get the paging to work for custom types on single-videos.php template?

I searched the forums but i cant find a solution for this specific problem. Specially since i can make it work on other templates.

Thanks in advance for any help
