Dear Susan,
The tip here is never to change the variables names! You may add new variables, change the labels, change the variables places in the questionnaire. When U open the rec file, epidata will ask U to update the rec file and everything will be there. Bur if you change the variable name in the qes file, EpiData will undestand that U erased the variable and created a new one, and your data will be lost "for ever". :( The chk files follows the same principle. The name of the varible is what matters. If you want to change a varible name in a dataset wiht lots of observations then you should look in the tools menu. There is an option to change variables names.
Best regards, Pedro Emmanuel Brasil

When I go back and edit an ques file add questions, etc. I want to retain the checks from the previous ques file, but incorporate new edits to ques file. How do I make data file w/o overwriting previous checks and/or creating new data file?
