Error activating Bon Toolkit for WordPress and get the following error:

Fatal error: Call to undefined function bon_toolkit_set_options() in
C:xampphtdocswordpresswp-contentpluginsbon-toolkitbon-toolkit.php
on line 410

When I go to line 410 I see this:

    return $options = bon_toolkit_set_options();
    }

I am new to programming, very very much a FNG. Any help and guidance is appreciated.
