I have 6 columns of numbers and I want to generate a random number in each column, but I want to restrict each column to a set range of numbers. Think of it like a lottery with total numbers 1-39, but since only certain numbers are the most likely to come up (say in column 1 only numbers 1-10 and column 2 numbers 5-15 and column 3 numbers 11-19 and so on) I want only randomize that range and direquard the other numbers. Also, if possible, not duplicate from one column to the next.
