Great graph, but I think that you added a || too many.
Shouldn't the graph command be:
twoway scatter mean rep78 || ///
rbar mean max rep78, bcolor(none) barw(0.2) || ///
rbar mean min rep78, bcolor(none) barw(0.2) || ///
rbar meanmsd meanpsd rep78 , barw(0.1) bcolor(red) /// removed ||
legend(off) ytitle(Miles per gallon) yla(, ang(h)) ///
note(red bars: mean +/- sd; empty bars show range)

My advice in a nutshell: forget any idea that -graph box- is the
way to do this. Produce your own results set and then build your
own graph as a set of calls to -twoway-.
sysuse auto, clear
statsby "su mpg" mean=r(mean) max=r(max) min=r(min) sd=r(sd), by(rep78)
// here k = 1; tune to choice
gen meanpsd = mean + sd
gen meanmsd = mean - sd
// use -line- or -connected- not -scatter-
twoway scatter mean rep78 || ///
rbar mean max rep78, bcolor(none) barw(0.2) || ///
rbar mean min rep78, bcolor(none) barw(0.2) || ///
rbar meanmsd meanpsd rep78 , barw(0.1) bcolor(red) || ///
legend(off) ytitle(Miles per gallon) yla(, ang(h)) ///
note(red bars: mean +/- sd; empty bars show range)
Not so long ago someone was complaining about the overlay idea
as unnatural. Here I designed a novel kind of graph purely
from very basic ingredients. It works!

I am not graphic at all. I cannot find a simple solution for my problem.
Probably the answer is simple, but I need help to find it. I want to create
a box graph with a line connecting the means (not the medians), but the
boxes have to cover the range (not the IQR)... also with boxes covering
k*std_deviation.
