Hi Satchit, Thankyou for what you've already done, but would you mind if I ask one last thing and then I'll leave you alone? In it's present form the output is fine, but I think I might like to have it output in this format;['c', 'b', 'a', 'd']. It is probably the most basic of questions to ask, but heck I've only been at this python stuff a week... : ) Calvin
