That works for single dimension arrays but I can't figure out the syntax for multi... I have been trying to use "answer_choices.insert" but cannot figure out the syntax eg answer_choices.insert([x][1],correct_ans_1) does not work.. Could you give me an example of Array#insert. using multidim. array Thanks, DC -- Posted via http://www.ruby-forum.com/.

First you need to get the inner array: answer_choices[x] then you get back an array. It's on this inner array where you want to insert, so (split in two steps): inner = answer_choices[x] inner.insert(0, correct_ans_1) Jesus.
