XmlPort problem: Value not expected

Hi all,

I have a problem when i want to import a certain document whit an xmlport.

Hier is a part of my Xmlport

And this is a part of Xml document

When i try to run come this error

The problem is just with documents which have multipel <date_time_period_details>.

Know anyone how can I solve thie problem?

Did you allow for multiple occurrences?
