I am trying to assemble an array of month names called “names\_of\_months\_paid”: 0 first\_month\_paid = client.first\_month\_paid 1 names\_of\_months\_paid = [] 2 number\_of\_months\_paid.times do 3 names\_of\_months\_paid \<\< first\_month\_paid.strftime("%B") 4 first\_month\_paid \>\> (1) 5 end For each payment (“number\_of\_months\_paid”), I need to store the name of the month, then store the name of the next month starting from “first\_month\_paid”. I seem to be having trouble advancing the month of “first\_month\_paid” on line 4 as I am left with an array of first month names. How might I get this to work? ---

Thanks for your suggestions Robert. Looks like this is all I needed to do: 4 first\_month\_paid = first\_month\_paid \>\> (1)
