I use a block of code like this wherever I need it:

PHP Code:
// Construct Page Navigation
$total = $dmEntry->viewTotalEntries($userid, $whereClause, $canViewPrivate);
$url = "viewblog.php?{$sID}userid=$userid";
$offset = ($vbulletin->GPC['page'] - 1) * $vbulletin->GPC['pp'];
$limit = "$offset, " . $vbulletin->GPC['pp'];
$pageNavigation = construct_page_nav($vbulletin->GPC['page'],
    $vbulletin->GPC['pp'],     $total,    $url, '&pp=' . $vbulletin->GPC['pp']
); 
You should only have to edit $total and $url for this to work. Make sure you have
PHP Code:
$vbulletin->input->clean_array_gpc('g', array(
    'pp' => TYPE_UINT,
    'page' => TYPE_UINT
)); 
in your code as well, and they SHOULD have default values... I use this function I wrote becuase I am lazy:
PHP Code:
defaultGPC( array(
    'pp' => $vbulletin->options['blog_max_entry_display'],
    'page' => 1
)); 
the function
PHP Code:
function defaultGPC($data)
{
    global $vbulletin;
    foreach ($data as $key => $value)
    {
        if (!$vbulletin->GPC[$key])
        {
            $vbulletin->GPC[$key] = $value;
        }
    }
} 
If you aren't lazy, then just something like this:


Then placing something like:
PHP Code:
if (!$vbulletin->GPC['page'])
{
    $vbulletin->GPC['page'] = 1;
}
if (!$vbulletin->GPC['pp'])
{
    $vbulletin->GPC['pp'] = 15;
} 
does the exact same thing.

HTML Code:
<if condition="$pageNavigation"><div align="right" style="margin-bottom: 5px">$pageNavigation</div></if>
<!-- main table -->
<if condition="$pageNavigation"><div align="right" style="margin-top: 5px">$pageNavigation</div></if>
To display it.

I suggest you look in functions.php for the definition of the function.

    while ($news = $db->fetch_array($news1)) { 
        eval('$rowbits .= "' . fetch_template('site_v3_news_single') . '";'); 
    }

    function defaultGPC($data) 
    { 
    global $vbulletin; 
        foreach ($data as $key => $value) 
        { 
            if (!$vbulletin->GPC[$key]) 
            { 
                $vbulletin->GPC[$key] = $value; 
            } 
        } 
    }

    ));  

    // Construct Page Navigation 
    $total = $db->num_rows($news1); 
    $url = "index.php?page=news{$sID}";
