Default value (std) not working

Hi

When using the attribute std => ” to set a default value, it is not working. Nothing shows in the Custom Field.

This is an example array:

`array(
// Field name – Will be used as label
‘name’ => __( ‘Test Field’, ‘restauranttheme’ ),
// Field ID, i.e. the meta key
‘id’ => “{$prefix}test_filed”,
// Field description (optional)
‘desc’ => __( ‘Test Field’, ‘restauranttheme’ ),
‘type’ => ‘text’,
‘std’ => ‘test text’,
),

The field should show “test text” as default however it is not working. Its blank. Same goes for any other field I tried such as checkboxes.

Can anyone help?

Thanks
