When you declare `%fields` inside the scope of the `foreach $item (@pairs)` loop with `my`, its contents are private to that loop. Then you try to access `%fields` after the loop, but it doesn't contain anything since you're outside the closing bracket (scope) of the `for` loop. -w and `use strict` tell of such errors.	[reply]

With your `my` declaration in the foreach loop you declared the hash locally. So the values you put into it weren't known outside. With using `strict` something like this can't happen because perl will give you an error. Have a look here for something more on `my`. You can also do a Super Search	[reply] [d/l] [select]
