Hey guys,

I've been working on a poker hand recognition assignment and ive been playing around with it for a week getting one problem after the next. Below is my code I have so far.

```

I've posted before so you may have seen my code. Its different now as I am changing the way I search for my poker hand. Basically my problem is this. I run the program and the strangest thing happens. These are my results below. The first 4 cards are player hands. The next 5 is what comes on the board. and the bottom 9 is the order of the deck. As you can see it works fine right now however after runnning a couple more times....

I ran it a number of times but from the looks of it their appears to be no noticable pattern. I've got no clue as to whats going on so i was wonderin if someone could help me out here.
