winner picker

I bet horses. I use info that'a available on a horse race only within the last 10 minutes before the race starts. I use this info to choose which horses I think will come in first, second, third, fourth, & fifth. So, for example, in a race with 7 horses running, with this info I choose 1 & 2 to come in first, 1, 2, & 3 to come in second, 1, 2, 4, & 5 to come in third, 1, 2, 5, & 7 to come in fourth, & 3, 4, & 5 to come in fifth. With those picks I then come up with my possible bets. Since I only bet the multiple horse bets [the 'exotics'], it takes me a while to come up with the bets & I sometimes miss being able to place all of my bets before the race starts. So I'd like to have a program that I can plug in the numbers [like the example I gave you] & it will generate the bets. Obviously there can be no duplicate numbers within a single generated bet [a horse cannot come in second AND third in the same race]. And I would like the program to total all the bets in each category: all the 2 horse bets, all the 3 horse bets, all the 4 horse bets, & all the 5 horse bets. I also need the program to still work if I only want, for example, 3 & 4 horse bets or just 3 horse bets.
