Thank you for your reply

1. I use version 2.0.4.43 for Mac

Program Version: 2.0.4.43 r1156 Core version: 2.0.0.0 r1161 FPC Version: 2.6.4 Platform: i386-Darwin

2. Both dataforms have the same identical 10 sections. I have created 1 dataform with 10 sections and let 2 people insert data parallel.

3. I haven’t defined any key, but I have defined an ID as a variable for each subject. However, it is not used for coupling the two files.

This is what I did: Document -> Compare duplicate files -> (the new window pops up) -> Click on “Compare” -> Click on “Add files” -> select those 2 files -> select the sections I would like to compare

Thank you so much. Suparee Boonmanunt

Please inform us of: 1 the version of manager You are using. 2 are you working with sections on one dataform or a related system with fields and sections on all dataforms 3 have you defined a key, and if so is that used for coupling of the two project files?

You get the version from the help menu "copy version "

Dear all,

I am trying to compare the duplicate files. I did it for each section. In some sections with small number of fields and just integer, the comparison goes well. But in other sections with larger number of fields, the program always shows the message ?Access violation? and ask whether I will ignore it and continue and kill the program. I always choose to ignore and the program seems to work on something. But nothing has really happened.

Should I just wait, because the program is still working? Or should I fix something in the entries?

I would be very grateful if someone could suggest me what to do.

Kind regards, Suparee _______________________________________________ EpiData-list mailing list EpiData-list@lists.umanitoba.ca http://lists.umanitoba.ca/mailman/listinfo/epidata-list
