PHP – Error

Hi! Thanks for this great theme, but i ‘ve got a warning:
PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'vw_kids_customize_controls_register_scripts' not found or invalid function name in
which is caused from
add_action( 'customize_controls_enqueue_scripts', 'vw_kids_customize_controls_register_scripts' ); in file /inc/typography/ctypo.php
It sheems that there is no function with name: “vw_kids_customize_preview_enqueue_scripts”

Best regards
Konstantinos
