On the product listing page, I would like a bullet point list within each product to show attribute name and value (for a particular group - "Specification) e.g.

Specification
-------------

* Fixing Centres: 120.6mm
* Size: 147.9mm x 87.4mm x 31mm

I have already added these attributes and assigned values to them within Magento. Using the code below (found and tweaked with a bit of searching here), I can also output an array containing the attribute name, however I can't seem to get the 'front end' version of the name and the value:

```
$setId = $_product->getAttributeSetId(); // Attribute set Id
$groups = Mage::getModel('eav/entity_attribute_group')
    ->getResourceCollection()
    ->setAttributeSetFilter($setId)
    ->setSortOrder()
    ->load();

$attributeCodes = array();
foreach ($groups as $group) {
    if($group->getAttributeGroupName() == 'Specification'){ // set name
    //$groupName          = $group->getAttributeGroupName();
    //$groupId            = $group->getAttributeGroupId();

    $attributes = Mage::getResourceModel('catalog/product_attribute_collection')
        ->setAttributeGroupFilter($group->getId())
        ->addVisibleFilter()
        ->checkConfigurableProducts()
        ->load();
        if ($attributes->getSize() > 0) {
            foreach ($attributes->getItems() as $attribute) {
                /* @var $child Mage_Eav_Model_Entity_Attribute */
                $attributeCodes[] = $attribute->getAttributeCode();  
            }
        } 
    }
}
print_r($attributeCodes);

```

The above outputs `Array ( [0] => mounting_box_depth [1] => fixing_centres [2] => size )`

To get the value, I tried 

```
$attributeValue = Mage::getModel('catalog/product')
            ->load($_product->getId())
            ->getAttributeText(attributeCodes[0]);

```

But this doesn't seem to return anything at all. Any ideas?

As requested, list.phtml in its entirety below:
