If you just need to know the value of this parameter (server-side), it is enough to do $node->field_название_поля['und']['value'] (which may be different depending on your settings). Or just do var_dump($node->field_название_поля) to understand where exactly to look for

Use dpm() from the module devel will see many interesting things.
