[Plugin: NextGEN Gallery] What about this code adjusts my columns/rows?

I recently added the NextGen Gallery Custom Fields to my HTML code, in order to make my thumbnails link to a custom URL (viewgallery.php). It works perfectly, except for one issue: something within this code makes my thumbnails line up in one long column, instead of nice rows of 4 that they used to be in. Does anyone know what to change within this code that will format my thumbnails into rows again?

<div id=”ngg-image-<?php echo $image->pid ?>” class=”ngg-gallery-thumbnail-box” <?php echo $image->style ?> >

<div class=”ngg-gallery-thumbnail” >
ngg_custom_fields[“Custom Link”]; ?>”
title=”<?php echo $image->description ?>”
<?php echo $image->thumbcode ?> >
<img title=”<?php echo $image->alttext ?>”
alt=”<?php echo $image->alttext ?>” src=”<?php echo $image->
thumbnailURL ?>”
<?php echo $image->size ?> />

ngg_custom_fields[“Custom Link”]; ?>”>
<?php echo $image->alttext ?>
</div>

Thanks for any help you can give!
