I am trying to place space for ad after 1st post so tried following code
In the "postbit" or "postbit_legacy", add to the end:

<vb:if condition="(THIS_SCRIPT == showthread) AND ($post[postcount] == '1')">
<div class="attachments">
<div style="width: 100%; text-align: center">
Your text here
</div>
</div>
</vb:if>

When i try to save am getting the below error..why?

You may not use the function parsePhrase()!!!
With a few exceptions, function calls are not permitted in template conditional expressions. Please go back and re-write this expression.

The following functions are allowed in template conditional expressions:
and() or() xor() in_array() is_array() is_numeric() isset() empty() defined() array() can_moderate() can_moderate_calendar() exec_switch_bg() is_browser() is_member_of() construct_phrase() iif()
