Using preprocess node variable in page.tpl.php I've set up a couple of variables in my template_preprocess_node(). How can I access them within a page template? I can access the $node variable, but it doesn't seem to have been preprocessed.  

How can I force preprocessing?
The node variable for page templates is set in template_preprocess_page

You should override that function in your theme
