Select random object
Is there a way to randomly select object?
I have 9 squares named, let's say: obj1, obj2, obj3, ..., obj9. They are part of the puzzle and I want to select them randomly. If I create a list with given objects it consists of object values but I need names. I also cannot generate some "i" and use it as obji or something like that.
I attached my applet for better explanation - when person enter correct result, one of the squares disapeare but it's always on the same position for the same task. (first task is to round number on two significant digits - always square 7, the second is to round number on two decimal places - always 8)
