[Plugin: Special Recent Posts] Unknown code error in template

Hi.
I’m trying to add SRP to my template, showing in a 2 by 4 layout where SRP fills a row left to right before continuing on the next row below.
I need it to get the posts from cat 82, to determine how many posts are in the cat, and to increase the SRP post offset by 1 after showing a post. It needs to keep making new rows until it has displayed 8 posts. That should result in a table 4 rows high.

I belive I’m getting close to a solution for this, but it seems I’m getting a PHP error on the line containing endwhile; endif;.
Would someone be so kind and have a look at this and lend a hand?

<?php //Get post count and set offsetcount to 0
$count = get_category(82)->count ; $offsetcount= 0 ; ?>

<tbody><table><tr>
<?php //Start and loop query while cat has posts and number of shown posts are less than 8, place it in 2 table columns
	if(($offsetcount < 8) && ($offsetcount < $count)) : while (($offsetcount < 8) && ($offsetcount < $count)) { ?>
<td style="width: 50%;" align="left" valign="top">

<?php
// Defining SRP options.
$args = array(
    'srp_number_post_option'  => 1,
    'srp_thumbnail_option'    => 'yes',
    'srp_thumbnail_wdg_width' => '200',
    'srp_thumbnail_wdg_height' => '140',
    'srp_title_hide' => 'yes',
    'srp_wdg_excerpt_length_mode' => 'chars',
    'srp_wdg_excerpt_length' => '230',
    'srp_filter_cat_option' => '82',
    'srp_wdg_excerpt_length' => '230',
    'srp_post_global_offset_option' => $offsetcount,
    'srp_wdg_excerpt_length' => '230',
);
		if(function_exists('special_recent_posts')) {
			special_recent_posts($args);
		};
?>
<?php //Add 1 to offsetcount before closing table column
$offsetcount = $offsetcount + 1 ;  ?>
</td>
<?php	    endwhile; endif; ?>
</tr></tbody></table>
