How to work with MultiMapping

I need to map my message types

source

<PersonInputMessageType>
   <persons>
      <person>
         <name>Test1</name>
      </person>
      <person>
         <name>Test2</name>
      </person>
   </persons>
</PersonInputMessageType>

target

<PersonMessageType>
   <person>
      <name>Test1</name>
   </person>
</PersonMessageType>
<PersonMessageType>
   <person>
      <name>Test2</name>
   </person>
</PersonMessageType>

I created a visual mapping where I mapped fields

pesron->person, name -> name.

The result is

<PersonMessageType>
   <person>
      <name>Test1</name>
   </person>
</PersonMessageType>

What step did I miss?
