Dear Statalisters

i would like to seek help from you guys. i have a variable which varies across countries over time. say i have 100 countries in year 2000 for a variable X. i want to  create a sum of variable X over all countries leaving the observation of nth country. this i need to do for each country. for example i have

country                 year            x               Sum(x)
Australia                2000          6                    16
New Zealand         2000          4                    18
United States         2000          8                    14
UK                         2000          3                    19 
China                     2000          1                    21

i would like to get a command which gives me the values in the last column. for Australia the values in the last column is 16 (=4+8+3+1), for New Zealand it is 18 (=6+8+3+1), for United States it is 14 (=6+4+3+1) and for other countries it follows the same pattern. i would like to do this for all the countries in my sample and for every year.


thanks
sanjesh
