Set bindings to two separate datasets

Thank you in advance for any feedback!

I am passing a datasource that contains two datasets. On my report under Bindings on the initial report I am using the following expression to set up the datasource of the table =ReportItem.DataObject.RawData.GetValue("states",true), this recognizes dataset(0) without any problem.  Now I need to set another table to dataset(1) =ReportItem.DataObject.RawData.GetValue("snapshotObj",true), but this is not being recognized, so I am thinking that I my code is not looking at dataset(1).  How can I do this?

Thank you,
