مشكلة الميثود creatOrder لاتجمع قيمة الفاتورة شكل صحيح

انشئت ميثود create order ومن المفترض بعد ما بيختار العميل الطلبات بتترسل معلومات العميل المدخلة والطلبات المختارة الى هذه الميثود وحساب السعر الاجمالي 

ولكن المشكلة انو بتطبع الطلب الاخير اللي اختارو العميل ما بتطبع كل الطلبات وايضا ما بتحسب السعر الاجمالي ايش الحل؟
