[support] cck text select showing key instead of label

[Christopher M. Jones]

Actually, it's a computed field that's showing the key. I've got a 
multiple select Text widget, and a computed field that concatenates all 
of the selected items into a formatted string:

foreach( $node->field_medical_service as $item ){
   $list[] = $item['value'];
}
$res = implode( ' & ', $list );
$node_field[0]['value'] = $res;

But this gets the key value of the selection, and not the label. I need 
the label. Should I be accessing something different from 'value'? Is 
anything else available to me in the computed field?
