Conditional for after first post of a thread

[skor]

I am trying to put some text only after the first post in a thread for a specific forum . I've tried...

<if condition="$forum['forumid'] == 24 AND !$GLOBALS['FIRSTPOSTID']">text here</if>

the only issue I am having is that it's appearing after the first post on every page for a thread that has multiple pages.

is there a conditional that would include it only after the first post of the whole thread so that it wouldn't show on the 2nd page?

thank you
