Ashley,
I just did this one for 4.2.3
{capture name=menu}
<ul>
<li><strong><a href="search.php?mode=search&including=all&price_m in=1& price_max=25&sort=price&sort_direction=0">
$1-$25</a></strong></li>
<li><strong>
<a href="search.php?mode=search&including=all&price_m in=26& price_max=50&sort=price&sort_direction=0">$26-$50</a></strong></li>
<li><strong>
<a href="search.php?mode=search&including=all&price_m in=51& price_max=75&sort=price&sort_direction=0">$51-$75</a></strong></li>
<li><strong>
<a href="search.php?mode=search&including=all&price_m in=76& price_max=100&sort=price&sort_direction=0">$76-100</a></strong></li>
<li><strong>
<a href="search.php?mode=search&including=all&price_m in=100& price_max=500&sort=price&sort_direction=0">$100+</a></strong></li>
</ul>
{assign var="additional_class" value="menu-categories-list"}
{/capture}
{include file="customer/menu_dialog.tpl" title="Shop By Price" content=$smarty.capture.menu}
