Question

Hello, I am trying to recreate a simple game called 'craps' on the computer. I am having trouble with the first part of the program, where the player bets for himself. Here are the rules for betting for yourself

*If the first roll of the dice results ina 7 or 11, then the player automatically wins

*If the first roll results in a 2, 3, or 12 then the player immediately looses

*if the first roll results with any other number (1,4,5,6,8,9,10), that number becomes the player's "point". At this point in the game, the player has a second chance to increase his bet. He cannot bet more than what he has. After he adjusts the bet, the player's goal is to now roll that "point" number again before rolling a 7. If he does, he wins. If he rolls a 7, he looses the bet.

*when the game ends (he looses or wins the bet), the player has the choice to play the game again, if he chooses yes it will reset him with $100.00 again.

Here is what i have so far. I am having trouble setting up three sceneraios ( he wins, he looses, or he goes onto the "point" round to win or lose). The if statement are not working correctly. I also need help in setting up a function say 'r' , which when he presses 'r' it will roll the dice for him and check. I appreciate your help, THANK YOU!
