The website cannot display the page

Hi,

I had a problem that I couldn’t see the video section in mobile.
I looked in some fourms and I foumd a code to change in the editor: index.php.

after I changed the code the website is not working at all! im completely stress from this.
I tried to write back the original code that I changed (see under) but the website is still not working.

please help me with this cause now I have no website at all!

the code that I changed in the index.php

(if( $video_background_section >0 && $video_background_section == $section_part && !$detect->isMobile() && !$detect->isTablet() )
get_template_part(‘home-sections/section’,$video_background_type.’-video’);
else
get_template_part(‘home-sections/section’,$section_part);
}
