Hi Nick,

Yes you were right about the syntax, thanks anyway Jesper. I've worked
out that the code:

egen double flows = sum(weight), by(lfs2)

Causes the code to for some reason delete all observations. Any idea
why that would be the case? In this case lfs2 is a string variable, so
all I'm generating is a new set of variables "flows" that sums the
"weight" of observations by lfs2. Is there anyway I can produce the
same result of this line of code without using egen or sum(weight)?
I'm pretty sure the problem's with one of these two commands.

Many thanks,

Fiona.
