Re: list values of specific hash keys

I'm going to take a stab in the dark and assume you're using strict (as you should).

That should be

foreach my $key (@keys){

Even though $key is automatically localized to the loop, you still need to declare it.

Hi @keys is defined elsewhere and contains strings and declaring keys outside doesn't help. If I print $key indside the foreach loop it has the correct values, but for some reason using it in the line `my $value = $hash{$key};` it doesen't work. If I enter the key manually in `my $value = $hash{"1234567"};` it works. \Sorenjul	[reply] [d/l] [select]
