Hi, I need help with a program I'm trying to right where I need to get specific values from a hash table and return them. I'll try my best to explain where I have to pull these elements from. The hash table has the structure:
%hash -> $variable_name -> 'fixed name(s)' -> value
I'm trying to assign the "value" to a scalar and return it but so far I'm not having any luck. $variable_name is being generated by a foreach loop and is definitely working. I've been trying code along the lines of
my $value = values %{$hash{$variable_name}{'fixed name'}}; print $value;
But this gives me "0". Which it's not. print Dumper %hash shows a nice hash table containing all the data it should so I know it's there. Can someone tell me what I'm doing wrong here?
