That's not how hashes work. A key can only appear once in a hash.	[reply]

Hi, this won't work as you use the same keys. `$VAR1 = { 'names' => 'mary', 'names' => 'john', 'names' => 'Doe', 'names => '' };` [download] Better try to make an array of hashes which would look like this: `$VAR1 = [ { 'names' => 'mary'}, { 'names' => 'john'}, { 'names' => 'Doe'}, { 'names => ''} ];` [download] or `$VAR1 = { 'names' => ['mary','john','Doe','']}; ];` [download]	[reply] [d/l] [select]

I know, wish it could be return as: `$VAR1 = { 'names' => 'mary'}, { 'names' => 'john'}, { 'names' => 'Doe'}, { 'names => ''} ;` [download] }, {	[reply] [d/l]
