Hello,

Need help on counting array elements in Hash of Arrays. How to list number of keys with respective to container number ? 

%HoA = (
## unique keys => [ "Item", "Container number" ],
   key1 => [ "50001", "01" ],
   key2 => [ "50011", "02" ],
   key3 => [ "50010", "01" ],
   key4 => [ "50041", "02" ],
   key5 => [ "50301", "02" ],
   key6 => [ "50701", "09" ],
   key7 => [ "50801", "09" ],
       );

No. of keys in the Container 01 : 2
