iOS duplication total of Shopping Cart

[moumen]

Hi,
I'm working on implementation of reservation specials restaurants
but I have a problem of duplication of calculating the total.
so when i want to add any thinks to this View so the total will increased.
I try to find a solution, but .... : ( .
I put images for this problem.
