Asking for connection info...Why?

[eye5600]

I am trying to display a Crystal Report in the report viewer using the
cookbook per "ADO.NET Reports in Windows Form Viewers." After the sda.Fill
statement, the data is in the DataSet (I checked), but after the last
statement, a box pops up asking for db connectin info. Why? and how do I stop
it? Thanks.

DataSet dsRpt = new DataSet() ;
SqlDataAdapter sda = new SqlDataAdapter() ;
sda.SelectCommand = new SqlCommand("select * from deposits where division
='10055'", DB) ;
sda.Fill(dsRpt,"deposits") ;

div_dep_summary oRpt = new div_dep_summary() ;
oRpt.SetDataSource(dsRpt) ;
crViewer.ReportSource = oRpt ;
