IF - Command in Theme file is giving error - HELP!

I worked with GoDaddy to identify the bug but I have no experience in debugging php files or scripts. I continue to see HTTP 500 errors which is pointing the error on the theme. static-image.php is the file to be specific

/home/content/a2pnexwpnas02_data02/04/3446304/html/wp-content/themes/houzez/template-parts/page-headers/static-image.php - LINE 77 which is:

if( $adv_search_which_header_show[‘header_image’] != 0 ) {

Here is the whole if command:

if( $adv_search_which_header_show[‘header_image’] != 0 ) {
if( $adv_search_over_header_pages == ‘only_home’ ) {
if (is_front_page()) {
get_template_part(‘template-parts/advanced-search/desktop’, ‘type2’);
}
} else if( $adv_search_over_header_pages == ‘all_pages’ ) {
get_template_part(‘template-parts/advanced-search/desktop’, ‘type2’);

} else if ( $adv_search_over_header_pages == ‘only_innerpages’ ){
if (!is_front_page()) {
get_template_part(‘template-parts/advanced-search/desktop’, ‘type2’);
}
} else if( $adv_search_over_header_pages == ‘specific_pages’ ) {
if( is_page( $adv_search_selected_pages ) ) {
get_template_part(‘template-parts/advanced-search/desktop’, ‘type2’);
