Re^4: multi level hash terror - if statement to access specific elements

Removing the print doesn't help - it is printing every last name in the database table. I just want it to print the surname of 'Gay' when it finds the first name 'Gay'. Only surnames should be printed whose first name is 'Gay' It seems to be printing every surname in the table.

for my $key (keys %names){
for my $key2(keys $names{$key}){
if ($names{$key}{$key2}[0] = 'Gay'){
print "Last Name:".$names{$key}{$key2}[1]."\n";
}
}
}

Thanks for the help here :)

...Removing the print doesn't help ... = 'Gay' Why are you still using the assignment operator instead of the string equality comparison operator eq?	[reply]

Sorry that's a typo...but using the correct equality operator still results in all surnames getting printed	[reply]

Sorry that's a typo...but using the correct equality operator still results in all surnames getting printed Are all the surnames "Gay"? Is this what you have? `my %names = ( abe => { lincoln => [ 'Cheddar', 'Cheddar', ], }, george => { washington => [ 'Gay', 'Gay', ], }, ); for my $key ( keys %names ) { for my $key2 ( keys $names{$key} ) { if ( $names{$key}{$key2}[0] eq 'Gay' ) { print "Last Name:" . $names{$key}{$key2}[1] . "\n"; } } } __END__ Last Name:Gay` [download] There is no lincoln/cheddar printed	[reply] [d/l]

… the correct equality operator … Did you notice that `==` is not the correct equality operator? Most strings numerically evaluate to zero, so `'apples' == 'pears'` [download] is true, while `'apples' eq 'pears'` [download] is false.	[reply] [d/l] [select]
