bbcode with vb variable? stuck

[t c]

PHP Code:

<script language="JavaScript">new TextFade('{param}','verdana,arial,helvetica','2pt',true,false,'#$bbuserinfo[field5]','#{option}');</script> 


I am using a custom bbcode and I wish to grab a custom field from the profile that contains the users custom color.

I have tried what you see above with: $bbuserinfo[field5] , $post[field5] , $profile[field5]

I am officially stuck.

This option is a [fade=XXXXXX]text[/fade] that will fade from basic color to a custom color (XXXXXX).

Any and all help would be greatly appreciated.
