XF 2.1 Show items based on age

[Cupara]

I'm using this template code in a template modification, it works for the most part just not the comparison of the visitors age to the forum age limit set.

<xf:set var="$birthday" value="{{ $xf.visitor.Profile.birthday.age }}" />
<xf:foreach loop="$threads" value="$thread">
     <xf:if is="!{$thread.Forum.gt_ag_agegate} && {$birthday|number} > {$thread.Forum.gt_ag_agelimit}">
          <li class="block-row">
               <xf:macro template="thread_list_macros" name="item_new_posts" arg-thread="{$thread}" />
          </li>
     <xf:else />
          <li class="block-row">
               {{ phrase('gt_agegate_not_old_enough') }}
          </li>
     </xf:if>
</xf:foreach>

Could someone please take a look at this and give me an idea of what I'm doing wrong. Thanks to everyone who takes a look.

Figured it out, needed to use

OR

instead of

&&
