Did you do this step in the instructions? If so, is the field ID in that code the same as the field ID of the field named test1?

vB AdminCP -> Styles & Templates -> Style Manager -> (Select Style) -> Postbit Templates -> postbit

FIND:

<!-- / post $post[postid] popup menu -->

After it post:

<!-- post specs_menu -->
<div class="vbmenu_popup" id="specs_$post[postid]_menu" style="display:none">
<table cellpadding="4" cellspacing="1" border="0">
<tr>
<td class="thead">$post[username]'s PC Specs</td>
</tr>

<if condition="$post['field5']">
<tr><td class="vbmenu_option">Motherboard: $post[field5]</td></tr>
</if>
</table>
</div>
<!-- / post specs_menu -->
