Hi Ashley.

I'm pretty new to this whole thing myself (fresh out of college, started
my first job here in late December), but I've been working with Delphi
and QuickReports just about the whole time. I've picked up a few things,
and I might be able to help.

It sounds like you need to do the old Master-Detail report. I've done a
few of those. Here's what I'd do:
First, forget the group bands and SQL. You shouldn't need them.

Start by going into the data set of your stock database. Set the
MasterSource porperty to the data source of the member db, and set up
the MasterFields so that it matches the memberid fields of the two dbs.

In QuickReports, start with a detail band, and set it up to display
whatever you want from the member db. Then put a SubDetail band on the
report. Set its Master property to the QuickReport itself, and set its
DataSet to the Stock db. You should then be able to display info from
the stock db on the subdetail band.

If all goes well, the report should print out the info on each member,
followed by all entries from the stock db that relate to them.

Well, I hope this actually helped. If you've got any more questions (or
if I just confused you even more), please post them. You might even get
someone who knows what they're doing to reply. ;-)

Good Luck!
