load new header and footer

Hello,

I am trying to make a second template by copying page.php, I called it ‘page – bk’ this worked. But in this template I need to have a different header and footer. I copied the header.php and footer.php aswel. But they don’t seem to load in the new page. Am I doing this right?

I load the new header and footer with these lines:

get_header( 'header-bk' );
get_footer( 'footer-bk' );

the new footer and header are called header-bk , and footer-bk.

Thank you if you could help me.
