```Billy and Matt,
Thanks so much!
You both were very helpful. Billy I tired just collapsing across Gain
and Loss  and then reshape so that they are 2 variables, and it
worked!

Matt, I will also try your suggestion - it would be better if I can do
it without collapsing and reshaping...

Thanks so much!

The easiest way I've found to deal with these situations (since the normal solution typically evades me at the time I need it) is to create a dataset with the appropriate summary statistics and then use the -(asis)- optional argument to work around it.  Michael Mitchell's book is almost always helpful in these instances (available from StataPress).
