Fatal error

When I go to my client’s website, acgstructures.com, I get this fatal error.

Call to undefined function sketch_get_option() in /home/acgstruc/public_html/wp-content/themes/analyticallitechild/front-page.php on line 4

I go to that file and this is what’s there….

<?php global $themename; global $shortname; ?>
<?php
if ( ‘page’ == get_option( ‘show_on_front’ ) ) {
if (sketch_get_option($shortname.’_hide_frontlayout’) == ‘false’) {
global $shortname;
?>
<?php get_header(); ?>

$skebg_capsArr[] = array(“title”=>$skebg_imgT,”descp”=>$skebg_imgC);
}
?>

I don’t know enough about writing code to see what’s wrong…..PLEASE HELP!

I’ve already tried deactivating plugins and re-updating the newest version of WP.

Right now I have a maintenance page showing up so people don’t see the error.
