Exporting to epidata format - not valid boolean expression

Hello EpiData friends, Im having a little trouble that I would appreciate very much some help. I have a rec file which I would like to create a subset. I tried to use the EpiData entry data export, using the filter option. When I set the filter such as: hepato <> 2 it is ok. But when I set the filter as alt1 >= 42 ... or I set the filter as ... (alt >= 42) or (hepato <> 2) I get an error saying this is not a valid boolean expression. I tried in several different ways and I couldnt figure out what Im doing worng. Any tip? Abraço forte e que a força esteja com você, Dr. Pedro Emmanuel A. A. do Brasil Instituto de Pesquisa Clínica Evandro Chagas Fundação Oswaldo Cruz Rio de Janeiro - Brasil
