Meta Boxes Issue

Previous request for help has been resolved (changed themes fixed it), However, i have an odd issue with the Meta Boxes file. I read that I can change the labels etc in the meta-boxes.php file to reflect local situations etc (we don’t use many of the systems listed here). So, if I get:

array(
‘name’ => ‘property_vacuum_system’,
‘label’ => __(‘Vacuum System’, ‘epl’),
‘type’ => ‘radio’,
‘opts’ => array(
‘yes’ => __(‘Yes’, ‘epl’),
‘no’ => __(‘No’, ‘epl’)
),
),

and change it to:

array(

‘name’ => ‘property_electric_heating’,

‘label’ => __(‘Electric Heating’, ‘epl’),

‘type’ => ‘radio’,

‘opts’ => array(

‘yes’ => __(‘Yes’, ‘epl’),

‘no’ => __(‘No’, ‘epl’)

),
),

It no longer shows up on the property details page at all. This has happened with all of the ones I changed. I only change the two named areas on each eg;

‘property_vacuum_system’,
‘label’ => __(‘Vacuum System’, ‘epl’),

becomes
‘property_solar_panels’,
