ActionScript 3.0 :: Limit Amount Of Times Number Is Used In Its Random Range?

Create a 12x9 grid;Populate the cells with random numbers ranging from 1-9;Assign a symbol (custom graphic) to each cell depending upon which random number is generated in it;Limit the amount of times each number in the random range is used to 12.My question is simply this: how do I, using AS3, create a random number function that will only use each number in its range a maximum of 12 times (it is important to note that my grid consists of 108 cells using the numbers 1-9 exactly 12 times each)? So for example, if the random number function populates 12 cells with the number "4," it will then exclude that number from its remaining iterations.I am adhering to OOP standards so including script in actual timeline frames is not desirable.
