Dear all,

I am struggling to extract the value of a variable from a panel.

I have a panel where "tvar" is time (eg: 1971-2010, that is data for
40 years ) and "nvar" is the id of each panel (eg: 1,2,... 10, that is
data for 10 individuals). My variable of interest is X. I would like
to extract the value of X for individual 5 in 1995 and save it in a
local. I have tried to use the option "if" but did not work with
"local" but did nto work. So far, I managed to use the option "in"
with the command "local" but then I have to find the location of X in
1995 for individual 5 by hand.

Kind Regards,
