Eva,
When I updated margeff it works! But I downloaded the margeff package just a few hours ago after searching for margeff using the search command in Stata. Next time I want to download a package, should I download it from someplace else to get the latest version?
Thank you!
And also thanks to Richard Williams that also suggested to update which I then didn�t try since I just had downloaded the package
