li tags cannot be selected and do not have a value attribute defined. It would be more correct to use radio buttons or a dropdown to select a value. If you want to use li you could keep 2 global variables with the corresponding selected values which will be updated everytime some li is clicked:

var value1 = '0',
    value2 = '0';

$('.list li').click(function() {
    value1 = $(this).attr('value');
});

$('.list2 li').click(function() {
    value2 = $(this).attr('value');
});

$('#someButton').click(function() {
    alert('value1 = ' + value1 + ' | value2 = ' + value2);    
});

If you are asking about "select" box instead of "li" tag, you can easily grab the select variable with jQuery using .val()
