I don't hardly look at the script they're having problems with, until I know they checked for typos, which is usually the case.
That's why you hardly ever see me stung up with a problem and posting for a solution. I look for the dumbest of mistakes first, which usually if not always, thats what it is.
My scripts get all screwy and don't work too
My favorite mistake is when I copy/paste a script (to save time), then get hidden characters that break the script; always happens when I forget to check for it, always takes me a day or two to figure it out again (I really saved a lot of time!).
