SQL/RS 2K, VS .Net 2003 - several single resultset/dataset reports working
just fine, finally got some multiple-resultset/dataset reports working very
well, too.  today, however, i am creating a new one that isn't working, and i
can't yet determine why.  

i have 5 different datasets so far, each are command type text, each field
presents the data just fine in the Data tab.  I've created tables in the
Layout tab for each dataset, and dragged/dropped the fields into each
accordingly.  When I go into the Preview tab, each dataset/table is visible
only intermittently????   Meaning, I'm in Preview, and 3 of the five
datasets/tables are showing data, the other two are blank.  Now, if i hit
refresh, only two are showing data... AND one of them is one that wasn't
showing data a moment ago.  

I'm setting this thing up just like the three i did yesterday, which are
working just fine.

Can anybody provide any direction on this?  It's very, very important, and I
do appreciate any assistance.
