I did a search and on line 300, I made the change below.

function avia_responsive_menu()
{
var win = $(window), header = $(‘.responsive #header’);

if(!header.length) return;

var menu = header.find(‘.main_menu ul:eq(0)’),
first_level_items = menu.find(‘>li’).length,
bottom_menu = $(‘html’).is(‘.bottom_nav_header’),
//switchWidth = 767;
switchWidth = 1000;

if(first_level_items > 7 + header.find(‘#menu-item-search’).length && !bottom_menu)
{
switchWidth = 989;
header.addClass(‘mobile_menu_tablet’);
}

I also saw on line 1593 below which I did not change:
//plugin’s default options
var settings = {
switchWidth: 768,
topOptionText: ‘Select a page’,
indentString: ‘   ‘
};

But no luck. What did I do wrong? http://www.kennethbsmith.com/clients/abww/
