Hi Jens and Michael, I to some extent like Epidata. I had one question and one suggestion: I did it qes to rec to chk to entering data. After entering a few records, I want to change layout of the form. I have to change qes, then qes updates rec, but it kills my old rec, or make it rec.old. What can I do to only change layout of form without killing the records entered? Do not tell me to export and import... can it be an option that improves the form only, while keeping the entered data intact? Suggestion: when entering data, can you modify EpiData so that focused field is highlighted, AND corresponding field name (too far at the beginning of the line, separated by field description) also highlighted? It assures that data is entered to the right field. With regards, Phan Trieu Anh
