just a quick example of one think I'd like to do, I 
figured out why it was failing, it was just toking the 
last string twice instead of each string once.  I suspect 
it would require an extra parameter, but I'd like the 
feature anyways....

Thanks

$field_display_tok = strtok ( "$field_display", ',' );
  $field_val_tok = strtok ( "$field_val", ',' );
 
  // still need to set type properly
  while ( $field_display_tok && $field_val_tok )
  {
//    printf ( "field_edval:  $field_edval, fieldval_tok:  
$fieldval_tok\n");
    if ( $field_edval == $field_val_tok )
      printf ( "    <option value = \"" . 
$field_display_tok . "\" selected>" . $field_display_tok . 
"\n" );
    else
      printf ( "    <option value = \"" . 
$field_display_tok . "\">" . $field_display_tok . "\n" );
 
    $field_display_tok = strtok(",");
    $field_val_tok = strtok(",");
     printf ( "field_edval:  $field_edval, fieldval_tok:  
$field_val_tok\n");
  }
