I have noticed that when you copy & paste from these forums, that you get all the text on one line so it is vital that you make sure the code is exactly as we see it. Otherwise it wont work, period.
I mentioned this just the other day,in reply to someone elses mentioning another way as well, but thought it worth repeating both.
(1) If u cut and paste from a message, you can open wordpad, paste text, reselect and cut and paste from there, and it well be fine.
(2) click the quote link on the message the script u want is in, then cut and paste the script from the post text edit box, and it well be fine.
