hello everyone.
can someone please show me how can i set a range for the number type in the text box of a GUI. I have a text box in GUI that i want it to accept only number ranged from 1 to 7. if the user input a number outside of the range, the text box will become empty, and a dialog box tells the user to input only a number ranged from 1 to 7, then the user has to input a different number which satisfies the condition. when the number is within range, the system will accept the number and stores it in a variable. lets call the variable as aa. your help is very much appreciated.
