Then your data is different from what you tell us: `D:\ENV>perl -MData::Dumper -e "$ha = { a => 'A' }; $hb = { b => 'B' }; + $m = { %$ha, %$hb }; print Dumper( $m );" $VAR1 = { 'b' => 'B', 'a' => 'A' };` [download] holli You can lead your users to water, but alas, you cannot drown them.

I did a data dumper on $data_b and got this: `$VAR1 = [ { 'house' => 'main', 'number' => '0123', 'area' => 'north', 'code' => 'zip', }; ]` [download] And on $data_a was this: `$VAR1 = { 'fullname' => 'Ms Mary Lou', 'first' => 'Mary', 'last' => 'Lou', };` [download]	[reply] [d/l] [select]

As shown by its data dumper output, `$data_b` is a reference to an array. The referenced array has a single element: a reference to a hash with four elements as shown. Assuming a successful operation to merge the contents of the hash referenced by `$data_a`, what would you then want the data dumper output of `$data_b` to look like? Update: The Perl Data Structures Cookbook (perldsc) may prove helpful now and in the future. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]
