How to get CCK optionsfield value, if I have the key for that value? I have a CCK select list where I defined key|value pairs.

When I execute a node_load for that node, I only get the key (in my case an integer) stored in Drupal.

How can I get the value of that key easily? Is there a Drupal function?

something like, cck_value('field_name',$key) ?
Node_load will return fully-populated node object. 

Value of cck fields in node object are usualy accessed in this way: 

 $my_node_object = node_load($nid);
 $myVar = $my_node_object-&gt;field_your_field_name['0']['value']


You can see what $node object contain if you do 

dsm($my_node_object); // Devel module must be turned on


Hope this helps.
