getting section_id value selected by user in lightbox

In my lightbox I am trying to get the selected value that was selected in the section drop down and make it the header value. How can I get the selected value clicked by the user.

Also I would like to seed the two text areas in the lightbox form based on users name and phone how would I set these values.

// Settings for the Sheduler 
		function init() {
			var user = $('#cName').val();
			var sections=[
				          	{key:1, label:"Men's Cut"},
				          	{key:2, label:"Color"},
				          	{key:3, label:"Women's Cut"},
				          	{key:4, label:"Wax"},
				          	{key:5, label:"Child Cut (under 3 yrs old)"},
				          	{key:6, label:"Nails - Pedicure"},
				          	{key:7, label:"Nails - Manicure"},
				          	{key:8, label:"Other"}
