I ran this with Stata 11 MP, Mac OSX, using the -scheme s2color- (though I don't know how this makes a difference). Make sure there is a space between the double quotes in the line (location of space marked with a capital X below for illustration): if !inlist(`n', 1, 20, 40, 60 , 74) /// replace o`varname' = o`varname' + `" `n' "X" "' You may have lost that space when copy/pasting the code from your email client to your Stata do-file editor. __ Eric A.
