Piotr's followup: >But I don't realised that I can't open the related file twice. >When I open file with first command "relate", the same file couldn't be >opened in the next part of form. >Am I right? You have to experiment a bit. Actually I am not sure, what I scheduled was a principle. If one cannot have the same relate more than once, just save the fieldname after entry and perform relate in a third field: Principle: v1 set variable to "v1" and jump to v30 v2 set variable to "v2" and jump to v30 v3 ,,,,,....... etc v30 perform relate here regards Jens M.

How to tell which field made a relate ?

Piotr asked: My next problem is: if there is some way to get the name of field in calculation. I mean, I 'd like to set comment legal in relational file depended on reference which field was called from. i.e.: main file has question: Which medicine have you used for last 12 month? And there is multiply response so I'd like to use relational file. But the next quetion is: Which medicine ...ever used? And my problem is to have ONE file with the medicine, and in this file I should have an information about respondent, and form WHICH FIELD was calling. ------------------------------------------------------------------ Something along this line where you combine a global variable with a comment legal depending on its value should work, some experimentation needed: chk file: before file * note the global define fieldname ____________ global end id mustenter key unique end v1 after entry fieldname = "v1" relate id otherfile 1 end end v2 after entry fieldname = "v2" relate id otherfile end end otherfile's chk file: before file * note you can repeat a define to be able to use the file alone define fieldname _________ global end id key mustenter end moreinfo before entry comment legal 10 "no answer" 11 otherfiled end if fieldname = "v1" then comment legal 1 yes 2 no end endif if fieldname = "v2" then comment legal 11 yes 12 no end endif end end regards Jens Lauritsen Jens M.

Problem with division by zero
by epidata-list＠lists.umanitoba.ca 15 Oct '03

Hello! I have a problem with all known example "first", and BMI calculation. When I left blank field in "high" the warning "division by zero" is shown. The "ignoremissing" command is not included. The second question is why EpiData writes in check file command "missingvalue all [same name of labelblock]". It happens when I'm working "manually" with check and then I open check editor. My build is: 040903 Regards, Piotr -- Piotr Kołodziejczyk tel: +48604512362 e-mail: admiralek(a)o2.pl
