AKOForms with Community Builder

[FerretLife]

I am trying to make a form using AKOForms that uses "Mambo Special Fields".

I have read the manual and I was able to place the "Mambo Username" and "Mambo Usertype" fields into a form with no problem. Works fine. I was able to create a custom field that automatically places todays date in the form. Two problems.

1) The field can be changed. Is there a way to make these hidden fields or static fields that cannot be changed by the user?

2) I use Community Builder. I have searched and tried a number of different ways of defining custom fields that are based on Community Builder fields rather than standard Mambo fields (First Name and Last Name).
$formfields[801] = array (
"field_title" => "First Name",
"field_html" => "<input type='text' name='af_fieldname'
class='inputbox' style='af_fieldstyle' value='$my->firstname' />"
);
Does anyone know a way to make AKOForms look in Community Builder (comprofiler) for these fields?

Thanks.
