Hello Spigot, I have encountered a NumberFormatException while using a String[].

Integer.parseInt(indexList[x]) causing NumberFormatException => indexList[x] is not a valid integer. You're expecting your prizes string to be a list of integers separated by commas, but somewhere it either has two commas next to each other, or the string starts / ends with a comma. Both of these would be invalid: "3,4,5," "4,,6,7" Also there's no need to escape "," so change .split("\\,") to .split(",")
Right now, the prizes string is just "" because I don't have anything there. So are you saying I need something in the prizes string such as "5" for this to work? Edit: Worked, thank you.
