Uhm, so hello! We have this project in our CS course that states that we have to generate our own Bingo Game program, we can use help or we can let a person/people work on it as long as we can understand it. But I chose the latter part of doing it with my partner, but by just asking for help. So here it is, I have this code for generating a card in a bingo game. It has a range, e.g. (B=1-15, I=16=30.....) until O that's until the number 75 only. It's already fixed, the only problem is that when I generate a number in the column B, and the other columns as well, the numbers are repeating. I've spent a day to 3 thinking and experimenting on my program, but still it repeats the number on a column! Uhh, can you guys help me with these? I'm a beginner, thank you! I also tried putting it in variables, and validating it one-by-one, but still it doesn't work. :(
