So do you have two recordsets that you are using for these repeat regions? I think you should have the repeat regions setup like this:
<ul id="search-width" class="items">
<?php repeat region one start ?>
<li>
<a><img src=""/></a><br/>
<span> product name</span><br/>
<strong> productPrice</strong><br/>
<span> SKU </span><br/>
<span>ProductStock?></span><br/>
</li>
<?php repeat region one end ?>
<?php check for rows being even?>
<?php repeat region two start ?>
<li style="border-left:3px solid #cccccc;">
<a><img src=""/></a><br/>
<span> product name</span><br/>
<strong> productPrice</strong><br/>
<span> SKU </span><br/>
<span>ProductStock?></span><br/>
</li>
<?php repeat region two end ?>
<?php end check for rows being even?>
</ul>
This will result in a single unordered list with two sets of entries. The first set will display the total number of records that you specify in the first repeat region. The second will display the total number of rows specified in the second repeat region.
