Multiply with link type self does not work

Hi. I am usin latest release from here.
I need to multiply two fields in a request workitem
so i put it into aggregationitems.xml:

< AggregatorItem name="score_mult" operationType="Numeric" operation="Sum" linkType="Self" workItemType="Request">
< TargetItem name="Score"/>
< SourceItem name="DEV Score"/>
< SourceItem name="Customer Score"/>
< /AggregatorItem>

and it gives nothing. windows application log shows nothing too

Sorry. Operation is Multiple. Copied wrong version. So Sum does not work too :)

Multiply only works if all field types are "Double".
