Hi @Martinko6
I did a local test,here is my preview result:
My table is like this:
the 2 expression I use :
=Lookup(Fields!id.Value, Fields!id.Value, Fields!pricepool.Value, "DataSet2")
=Sum(Lookup(Fields!id.Value, Fields!id.Value, Fields!pricepool.Value, "DataSet2"))
Hope this can help you.
Best Regards,
Isabella
