need some help a little problem

In one of my skin in the navbar i can not find this code

<td class="vbmenu_control"><a href="calendar.php$session[sessionurl_q]">$vbphrase[calendar]</a></td>
<if condition="$show['popups']">

i have searched the word calendar to see if i was able to put it there and nothing came up. where would be the best place for me to stick the code at since i can not find the above in the navbar
