I am quite puzzled here. I have a program inwhich when the user clicks on the command button, a random line should appear but only once.
I am storing each line with different variables.
Right now i have the random line coming up but it is repeating itself.
For instance, when i click on the button, line 1 appear, then line 4, and them line 1 again. How can i stop the line 1 to show again?
