[amibroker] how to change volume in 1min. intraday data?

["gsmservplus" <domantas.rudys@xxxxxxxxx>]

hi,

i`ve got txt files with cme,cbot and nymex futures intraday 1 minute 
historical data. there are data in 
<<date,time,open,high,low,close,up,down>> formats. "up" is up volume 
and "down" is down volume. how can i uplode that data to amibroker 
through import wizard? because if i set in define field column 7 and 
column 8 like VOLUME in chart it reads only last "down" volume.
example : for @ES symbol   
2/13/08,1654,1350.75,1363.00,1344.25,1649.50,55,126
up is 55, down is 126, so, when i uplode to AB that data volume 
indicator reads 126. i would like to get 55+126= 181(total volume for 
that minute). how can i do it? or only way i`ve got to change all data 
in those files manually?

thanks
