{* Title *}
{block name='frontend_index_header_title'}{strip}
    {if $sCategoryContent.metaTitle}
        {$sCategoryContent.metaTitle|escapeHtml} | {{config name=sShopname}|escapeHtml}
    {elseif $sCategoryContent.title}
        {$sCategoryContent.title|escapeHtml} | {{config name=sShopname}|escapeHtml}
    {else}
        {$smarty.block.parent}
    {/if}
{/strip}{/block}

```

Kann mir jemand mal verraten warum hier auf **$sCategoryContent.titel** geprüft wird, wenn nirgendswo ein title an das Template übergeben wird?
