hummm...

The Ace does not turn to 1 if you go over 21... for example I had an ace hearts and and a 6 of spade, dealer drawn a 6 of clover for me and I busted.

The dealer is cheating

The interface is somewhat ho-hum; but that might be just getting accustomed to programming for a flash player. But this gives the "dealer" far too much of an advantage. In casino play, which I think this is supposed to emulate, the dealer is required to draw to 16 and stand on seventeen. He does not get to base his decision on the player's hand. (I understand that in informal rules, the dealer can use discretion but doesn't get to know the player's hand.) The way you have this set up the computer will stand on a low hand if it beats a player's hand when the player has opted to let the dealer risk busting and will hit an 18 or 19 if the player has 20. In essence, the computer is cheating and not allowing a close to fair chance of winning.

One Error

Everyone loves Blackjack, but I have one problem:

In your game, if I am dealt a Black Jack, and the dealer turns up 16, then hits a 5, we draw at 21. According to the real rules though, I would win once the dealer turned over 16.
