Picking random number without repeating (4 different attributes)
Hello to GS Community,
I would like to ask you:
I have 4 global attributes called A B C D. A has value of 1(real), B 2, C 3, D 4. That is the default. On a specific occasion, they should change their value random(1,4) but I do not want them to repeat ( A 2, B 3, C 1, D 1 is repeating) or in other words to make 1,2,3,4 in a random way. How to do that?
