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
