Hi Bill,
We recommended not to change the code because if you change the code then while updating to our new version all your customisation code will be lost. So better make child theme and first unhook the functions and the edit the code.

You may try this below code.

function attitude_javascripts() {
    wp_enqueue_script( 'the-script-handle', 
                       'path/to/file.js', 
                       array( 'jquery','other_script_that_we_depend_on' ), 
                       'scriptversion eg. 1.0', 
                       true);
}
add_action( 'wp_enqueue_scripts', 'attitude_javascripts' );

If you are unable to add then you may hire a developer to fix it.

Thank you!
