 $navbits = array();
$navbits[$parent] = 'MK1';

$navbits = construct_navbits($navbits);
eval('$navbar = "' . fetch_template('navbar') . '";');
eval('print_output("' . fetch_template('TEST') . '");');

change this to

 $navbits = array();
$navbits[$parent] = 'Mortal Combat blah blah';

$navbits = construct_navbits($navbits);
eval('$navbar = "' . fetch_template('navbar') . '";');
eval('print_output("' . fetch_template('MK1') . '");');
