请问这种嵌套里 currentstyle="display:block;"为何无法输出，请问要怎么改进
{eyou:channelartlist typeid='82' row="3" type ='sonself' currentstyle="display:block;"}
<div class="new_group ovh hide" style="{$field.currentstyle}">
{eyou:arclist row='1' titlelen='30' infolen='160' orderby='add_time'}
<img src="{$field.litpic}" alt="{$field.title}" title="{$field.title}" width="540" height="360" class="fl mr20">
{/eyou:arclist}
<ul class="flex_1 index_news_list ovh">
{eyou:arclist row='3' titlelen='30' infolen='160' orderby='add_time'}
<li class="ovh" data-img="{$field.litpic}">
<a title="" href="{$field.arcurl}">
<img src="{$field.litpic}" title="{$field.title}" class="fl mr20" width="150" height="100">
<div class="txt ovh">
<h3 class="tit">{$field.title}</h3>
<p class="c_919191 ellipsis mt15">{$field.seo_description|html_msubstr=###,0,120,true}</p>
</div>
