Solution 1

This should do it:

var sum = 0;
$('#activities').nextAll('.rows').find('.value').each(function() {
    var n = parseInt($(this).text(), 10); 
    if (!isNaN(n)) sum += n; 
});

Solution 2

you can select .rows elements directly instead of traversing the DOM by using multiple next() methods, try the following:

var sum = 0;  
$(".rows .value").each(function(){
       var val = parseInt($(this).text(), 10)
       if (!isNaN(val)) {
            sum += val
       }          
})

Solution 4

To get each individual value in an array:

var values = $(".value", ".rows").map(function(i, e) {
    return parseInt(e.innerHTML, 10);
})​;

FIDDLE

To get the combined sum of the values

var value = 0;
$.each($(".value", ".rows"), function(i,e) {
    value += parseInt(e.innerHTML, 10);
});
