I've got it worked out. Here's the code:

{section name=cat_num loop=$categories}

  <FONT class="CategoriesList">{$categories[cat_num].category}</FONT>


  {if $current_category.categoryid == $categories[cat_num].categoryid}
	
    {section name=subcat_num loop=$subcategories}
    
      <FONT class="CategoriesList"><span class="small">&gt; </span>{$subcategories[subcat_num].category}</FONT>


    {/section}
	
  {elseif $current_category.parentid == $categories[cat_num].categoryid}

    {section name=subcat_num loop=$allcategories}
		
      {if $allcategories[subcat_num].parentid eq $location[1].1|replace:"home.php?cat=":""}

        <FONT class="CategoriesList"><span class="small">&gt; </span>{ $allcategories[subcat_num].category|escape }</font>


      {/if}
			
    {/section}

  {/if}

{/section}
