CCK field in node template If I have a custom CCK field, for example "temperature", is there any way I can directly call it from the node template? Like would there be a $temperature variable?

Thanks!
You can access it directly from the node variable like: $node->field_temperature[0]['view'].

If you want to see what values are actually on the node, I'd suggest var_dump($node); in the template to check out what fields/values you can access.
