            var sum = 0
            //find the TC elements in the current row and sum it 
            $(this).find('.TC').each(function () {
                var tc = $(this).text();
                if (!isNaN(tc) && tc.length !== 0) {
                    sum += parseFloat(tc);
                }
            });
            //set the value of currents rows sum to the TotalHrs element in the current row
            $('.TbTotalHrs1', this).html(sum);
        });

What I have tried:

Hello guys, need a little help here, trying to sum up the TbDay11,TbDay21,TbDay31... etc.. and put the Total in TbTotalHrs1 using jquery as i want this to happen without refreshing the whole page.
Table is has ID of 'myPostTable' and is wrapped in an UpdatePanel if that matters.
I'm new to jquery and struggling to figure this out.. any help would be appreciated.
