When a user complete the swap, he can then change the status by going to his myswap option. There will be list box so that he can easily change status. 3. When the status changed to "swap successfull", then the said item will not be shown in view swap page so that other users can't choose it to swap and the swap count for participated users will be increased by 1. 4.
