You also have a semi-colon at the end of the line which is probably unnecessary. Your use of the -, format()- option doesn't look right to either as you appear to be using it twice, once without specifying any actual format and a second time you use the abbreviated form, but don't use the correct format. Finally you can combine the -sort- and -by- into one by using -bysort-, so try bysort cmanew: table vismin lf_act weight = wt, c(sum counter) format(%9.0) col row center Neil -- "Our civilization would be pitifully immature without the intellectual revolution led by Darwin" - Motoo Kimura, The Neutral Theory of Molecular Evolution Email - nshephard@gmail.com Website - http://kimura-no-ip.org/ Photos - http://www.flickr.com/photos/slackline/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
