هل المجموع الكلى ده عبارة عن متغير فى الجافاسكريت ؟ و عاوز لما تختار واحد من التشيكبوكس يزود عليه ؟ لو كده يبقى ممكن تستخدم الجى كويرى var score = 10; $('#checkbox_id').change(function(){ $this = this; if($this.attr('checked')=='checked'){ score += 5; }else{ score -= 5; } }); ده على حسب فهمى للمشكلة

كل ده بالجافاسكريبت اول حاجة اعمل متغير var total = 10; و دالة تعمل ابديت للمكان اللى بيظهر فيه التوتال function update_total(){ $('#total_id').html(total+'$'); }
وبعدين اعمل دالة تزود و دالة تقلل فيه function total_increase(amount){ total += amount; update(); }
function total_decrease(amount){ total -= amount; update(); }
و بعدين اربط بقى مع كل تيك بوكس $(function(){ $('#checkbox_id').change(function(){ if($(this).attr('checked')=='checked'){ total_increase(5); }else{ total_decrease(5); } }); });
خلى بالك تغير السيليكتورز زى #checkbox_id #total_id بقيم الid الخاصة بيك
