Enfold child theme function.php

hello, I inserted in the functio.php file of the son theme this change:

$ avia_config [‘imgSize’] [‘widget’] = array (‘width’ => 36, ‘height’ => 36); // small preview pics eg sidebar news
$ avia_config [‘imgSize’] [‘square’] = array (‘width’ => 920, ‘height’ => 690); // small image for blogs
$ avia_config [‘imgSize’] [‘featured’] = array (‘width’ => 1500, ‘height’ => 430); // images for fullsize pages and fullsize slider
$ avia_config [‘imgSize’] [‘featured_large’] = array (‘width’ => 1500, ‘height’ => 630); // images for fullsize pages and fullsize slider
$ avia_config [‘imgSize’] [‘extra_large’] = array (‘width’ => 1500, ‘height’ => 1500, ‘crop’ => false); // images for fullscrren slider
$ avia_config [‘imgSize’] [‘portfolio’] = array (‘width’ => 495, ‘height’ => 400); // images for portfolio entries (2.3 column)
$ avia_config [‘imgSize’] [‘custom’] = array (‘width’ => 450, ‘height’ => 338); // images for portfolio entries (2.3 column)
$ avia_config [‘imgSize’] [‘portfolio_small’] = array (‘width’ => 260, ‘height’ => 185); // images for portfolio 4 columns
$ avia_config [‘imgSize’] [‘gallery’] = array (‘width’ => 920, ‘height’ => 690); // images for portfolio entries (2.3 column)
$ avia_config [‘imgSize’] [‘magazine’] = array (‘width’ => 920, ‘height’ => 690); // images for magazines
$ avia_config [‘imgSize’] [‘masonry’] = array (‘width’ => 920, ‘height’ => 690, ‘crop’ => false); // images for fullscreen masonry
$ avia_config [‘imgSize’] [‘entry_with_sidebar’] = array (‘width’ => 920, ‘height’ => 690); // big images for blog and page entries
$ avia_config [‘imgSize’] [‘entry_without_sidebar’] = array (‘width’ => 920, ‘height’ => 690); // images for fullsize pages and fullsize slider
$ avia_config [‘imgSize’] = apply_filters (‘avf_modify_thumb_size’, $ avia_config [‘imgSize’]);

$ avia_config [‘selectableImgSize’] = array (
‘square’ => __ (‘Square’, ‘avia_framework’),
‘featured’ => __ (‘Featured Thin’, ‘avia_framework’),
‘featured_large’ => __ (‘Featured Large’, ‘avia_framework’),
‘portfolio’ => __ (‘Portfolio’, ‘avia_framework’),
‘gallery’ => __ (‘Gallery’, ‘avia_framework’),
‘entry_with_sidebar’ => __ (‘Entry with Sidebar’, ‘avia_framework’),
‘entry_without_sidebar’ => __ (‘Entry without Sidebar’, ‘avia_framework’),
‘extra_large’ => __ (‘Fullscreen Sections / Sliders’, ‘avia_framework’),

);

The problem is that it does not accept the change. The others inserted all work. I also tried to reload the images, but always sees the settings of the parent theme.
