add selected uc attribute price values for product which are added in cart block.

current code if (!empty($display_item)) {
$attributes = isset($item->data['attributes'])?$item->data['attributes']:NULL;
$total += $display_item['#total'];
$total_items += $display_item['qty']['#default_value'];
$items[] = array(
'nid' => $display_item['nid']['#value'],
'qty' => t('@qty×', array('@qty' => $display_item['qty']['#default_value'])),
'title' => $display_item['title']['#markup'],
'descr' => isset($display_item['description']['#markup']) ? $display_item['description']['#markup'] : FALSE,
'link' => url('node/' . $item->nid),
'item' => $item,
'image' => uc_product_get_picture($display_item['nid']['#value'], 'cart'),
'node' => node_load($item->nid),
'total' => $display_item['#total'],
'remove_link' => l(t('Remove product'),
UC_AJAX_CART_REMOVE_CALLBACK,
array(
'attributes' => array(
'onclick' => "ajaxCartBlockUIRemove(this.href); return false;",
'class' => array('remove-cart-link', 'remove-cart-link-' . $display_item['nid']['#value']),
),
here 'descr' => isset($display_item['description']['#markup']) ? $display_item['description']['#markup'] : FALSE,
this code return the value of label of the selected attribute but not attribute price value..
Please anyone suggest for this task..
Thanks in advance
