Well, that script did not work for me, but the following did work below. Basically, the colored text is for the form application link and the black text is for the normal new thread button. Change XX to the forum where the form is in. I cannot remember the ELSE tag which I believe is simple. I'm too tired right now.
Find <!-- controls above thread list --> in FORUMDISPLAY.
Code:
<if condition="$foruminfo[forumid] == XX">
<!-- controls above thread list -->
<table cellpadding="0" cellspacing="0" border="0" width="100%" style="margin-bottom:3px">
<tr valign="bottom">
<td class="smallfont"><if condition="$show['newthreadlink']"><a href="newthread.php?do=formname" rel="nofollow"><img src="$stylevar[imgdir_button]/newthread.gif" alt="$vbphrase[post_new_thread]" border="0" /></a><else /> </if></td>
<if condition="$pagenav"><td align="$stylevar[right]">$pagenav</td></if>
</tr>
</table>
<!-- / controls above thread list -->
</if>
<if condition="$foruminfo[forumid] <> XX">
<!-- controls above thread list -->
<table cellpadding="0" cellspacing="0" border="0" width="100%" style="margin-bottom:3px">
<tr valign="bottom">
<td class="smallfont"><if condition="$show['newthreadlink']"><a href="newthread.php?$session[sessionurl]do=newthread&f=$foruminfo[forumid]" rel="nofollow"><img src="$stylevar[imgdir_button]/newthread.gif" alt="$vbphrase[post_new_thread]" border="0" /></a><else /> </if></td>
<if condition="$pagenav"><td align="$stylevar[right]">$pagenav</td></if>
</tr>
</table>
<!-- / controls above thread list -->
</if>
