Card Game

[nadeali]

i've spent a lot of time making this game; yet it does not give the desired output. I know its a lot to ask, but can someone read the whole code and help?
its a game in which every player is dealt 5 cards each from the deck and then turn by turn each player throws a card and picks a card either from the pile or from the deck to maintain the minimum sum of their 5 cards. in the end the player with the least sum of 5 cards, wins.
