Looping issue

I have an input schema similar to this:

Header

--itemNumber

Detail

--lineItemNum

--Status

I am mapping to a schema similar to this:

root

----itemNumber

----Notes

Item number maps straight across.  lineItemNum and Status are concatenated and separated via a comma and each loop on detail is separated by a ~.  I am using a concatenate functoid with 4 parameters: lineItemNumber, ",", Status, and '~'.  I am then using a cumulative concatenate on the result of that and finally a value mapper to the Notes field.

Instead of getting:

<root>

   <itemNumber> 123    </itemNumber>

   <Notes> 1,Active~2,Cancelled~3,Active </Notes>

</root>

I am getting:

<root>

   <itemNumber> 123    </itemNumber>

   <itemNumber> 123    </itemNumber>

   <Notes> 1,Active~2,Cancelled~3,Active </Notes>

   <Notes> 1,Active~2,Cancelled~3,Active </Notes>

</root>

Any ideas?

Thanks
