Hi All,

Can I create an associative array where the key is the value of another
associative array?

Say I have the following:

$FORM{'name'} = 'JohnDoe';

Then, I want to create $names{$FORM{'name'}} = some value

That is not working, but I want to create an associative array where
the key is the value from another associative array without having to
assign an interium variable........

Any help with the syntax?

Thanks.

what do you mean by 'not working'? what are your results?

What do you mean, 'not working?' This works:

#!/usr/bin/perl
use warnings; use strict;

my %form;
$form{'name'} = 'JohnDoe';

my %names;
$names{$form{'name'}} = 'some value';

print $names{'JohnDoe'};
__END__

#### output: "some value"

Show us some more code, or tell us more specifically what the problem
(and/or goal) is.

Your syntax is perfectly fine. You claim that it is "not working" -- not
very useful. (Do you take your car to the mechanic, say "it's not
working", and walk away?)
