Report Builder Linking Problem

I've created a report that links from JobHead (the master table) to
OrderDtl (by PartNum) to OrderRel (by OrderNum/OrderLine).

But, the totals for the OrderRel table do not work correctly even
though the fields show up correctly in the record band. The totals
for OrderRep seem to be only for the records linked to the FIRST
record in OrderDtl.

Does anyone know if 3 level deep links such as...

Jobhead
OrderDtl
OrderRel

...work in Report Builder? Or any ideas what I might be doing wrong?
I've tried linking from OrderDtl to OrderRel by different fields
without success.

Any help would be appreciated,
