关于volist标签嵌套if标签出现错误的解决方法

错误写法：

<div class="hflz">
    <volist name="arr1" id="vo">
        <div class="lz">
            <div class="name">{$vo.name}</div>
            <div class="cont">{$vo.cont}</div>
            <a href="javascript:void(0)" class="hf" title="{$vo.id}">回复</a>
            <a href="javascript:void(0)" class="hf1">收起回复</a>
        </div>
        <div class="hfcz">
            <volist name="arr2" id="vo1" key="num">
                <if condition="$vo.id eq $vo1.czid">
                    <div>{$vo1.cont}</div>
                </if>
            </volist>
        </div>
        <div class="re">
            <form action="" method="post">
                <textarea name="huifu"></textarea>
                <input type="hidden" value="{$vo.id}" name="lz">
                <label><a href="javascript:void(0)" class="fabiao1">发表</a></label>
            </form>
        </div>
    </volist>
</div>     <!--回复后显示回复内容的容器-->

正确写法：

<div class="hflz">
    <volist name="arr1" id="vo">
        <div class="lz">
            <div class="name">{$vo.name}</div>
            <div class="cont">{$vo.cont}</div>
            <a href="javascript:void(0)" class="hf" title="{$vo.id}">回复</a>
            <a href="javascript:void(0)" class="hf1">收起回复</a>
        </div>
        <div class="hfcz">
            <volist name="arr2" id="vo1" key="num">
                <if condition="$vo.id eq $vo1['czid']">            <!--修改此处-->
                    <div>{$vo1.cont}</div>
                </if>
            </volist>
        </div>
        <div class="re">
            <form action="" method="post">
                <textarea name="huifu"></textarea>
                <input type="hidden" value="{$vo.id}" name="lz">
                <label><a href="javascript:void(0)" class="fabiao1">发表</a></label>
            </form>
        </div>
    </volist>
</div>     <!--回复后显示回复内容的容器-->
