wp_enqueue_script | Help me figure out what is causing jQuery is not defined

Long shot, but aren’t you by any chance typing $ instead of jQuery, or vice versa?

(function($) {    
    // Use $() inside of this function    
    $('#selector') ...    
})(jQuery);

or

// Otherwise use jQuery()
jQuery('#selector') ...
