Hi again David, As I mentioned, I'm not sure I understand this syntax enough to be able to manipulate it and was wondering if you could kindly help me a little more. Here's my exact problem: The variables I have start from v0915 and continue to v1005 and I need to rename every 5th variable in this list starting from v0917. The variables to be renamed to are: cost_a, cost_b....cost_n. How would I modify the syntax you sent me for this scenario?
