I know why my code was not working. And liked you guys said it was my logic.(Its hard for me to learn code with out really writing it) When I was creating if else statements I notice my do while loop was in conflict with my if else statements. What I wanted to know was if there was another better why of writing this loop. I use the do while loop cause it seems more logical to me then a while or for statement. Here is my output if you wanted to see what happens. Thanks Again everyone.

Correct! You guess correctly guessed 43
Play again? 1 for YES: 0 for NO: 1
