[Style Customization] Userfield Postbit Variable Depth in new Template?

[Dygear]

I've made a new, non-standard postbit template called postbit_certification, with the following code:

<vb:if condition="$post['field6']=='AEMT-P'">
					<dt>Certification</dt> <dd><abbr style="color: #0000FF;" title="Advanced Emergency Medical Technician - Paramedic">AEMT-P</abbr></dd>
<vb:elseif condition="$post['field6']=='AEMT-CC'" />
					<dt>Certification</dt> <dd><abbr style="color: #0000FF;" title="Advanced Emergency Medical Technician - Critical Care">AEMT-CC</abbr></dd>
<vb:elseif condition="$post['field6']=='AEMT-I'" />
					<dt>Certification</dt> <dd><abbr style="color: #FF0000;" title="Advanced Emergency Medical Technician - Intermediate">AEMT-I</abbr></dd>
<vb:elseif condition="$post['field6']=='EMT-B'" />
					<dt>Certification</dt> <dd><abbr style="color: #FF0000;" title="Emergency Medical Technician - Basic">EMT-B</abbr></dd>
<vb:elseif condition="$post['field6']=='CFR'" />
					<dt>Certification</dt> <dd><abbr style="color: #000000;" title="Certified First Responder">CFR</abbr></dd>
<vb:elseif condition="$post['field6']=='CPR'" />
					<dt>Certification</dt> <dd><abbr style="color: #00A000;" title="Cardiopulmonary Resuscitation">CPR</abbr></dd>
<vb:else />
					<dt>Certification</dt> <dd>None</dd>
</vb:if>

Then I added this postbit_legeacy (as I'm using user details next to post, not above).

{vb:raw post.certification}

But there is no output at all from my addition when it's called from the vb:raw statement.

The set of statements however do work when they are placed directly inside of the postbit_legeacy code. Any idea what I'm doing wrong? Did I miss a step somewhere?

--------------- Added [DATE]1262631305[/DATE] at [TIME]1262631305[/TIME] ---------------

Simple question then.

What is the variable scope for $post? Can I use it in any postbit style? Keeping in mind that it's meant to be unique to that users post, and it's meant to reflect the posters' information.
