Looping check error

[Kigali1]

This code is part of my game to check for aces in the player's hand as part of a blackjack game. It's supposed to check hand, pval_hand, for any values that are '1' or '11' (since they would be aces) and keep track of them. ace1, ace2, ace3, & ace4 are there to keep track of which slot the 1st, 2nd, 3rd, & 4th ace(s) are being held. pindex is the index count of how many cards are in pval_hand and is 2 at this point in the game. pval_hand is a vector with 10 elements {11 11 0 0 0 0 0 0 0 0} at the beginning.

My problem is that it cycles once and finds the 1st & 2nd aces at the correct index, but after it cycles again it assigns those values to ace3 & ace4. What I want to happen is that ace1 keeps track of the 1st ace to show up in the player's hand, ace2 the 2nd ace, etc. i.e. if a player had the hand {11 3 2 11 0 0 0 0 0 0} ace1 = 1, ace2 = 4, ace3 = 0, ace4 = 0, and after one pass through the hand should be updated to {1 3 2 11 0 0 0 0 0 0} ace1 = 1, ace2 = 4, ace3 = 0, ace4 = 0. What actually happens is that after the 1st pass it updates to {1 3 2 11 0 0 0 0 0 0} ace1 = 1, ace2 = 4, ace3 = 1, ace4 = 4

 {
  phand = 0;	//sets base value of player's hand to 0

   {
    aceCheck = true;
   }

I will happily provide more code upon request, but I was trying to keep it reduced to only sections that are related to this individual problem. Again, I'm quite new to C++ (and programming in general) so any help is greatly appreciated.
