Dear Hans,
Thank you for asking; indeed the idno is key unique 1 in file.rec1 and key unique 2 in file.rec2 and file.rec 3.
I have tested the files using different computers (at least 3) they all work fine (sorry for not stating this in my previous request). However, the error occurs and continues to occur when I use my lap top (Vista) and yet this is my main tool to design the entire database.
Clearly, the error may not be associated with EpiData; but something to do with my laptop (with Vista, in particular). Are there any solutions or just ignore it?
Kind regards
Tieble

Dear Tieble:
Just to get it out of the way (apologies if it is too trivial a question): is your idno KEY UNIQUE in file1.rec and KEY in file2.rec? I am asking because I simulated it and get no error message.

Dear colleagues,
Is there a possible solution to avoid the error message "Error in IF expression; Cannot apply opGT to missing operands" during data entry under the check commands below? NB: (values and labels 0=No; 1=Yes) for varsv1
varsv1 COMMENT LEGAL USE label_varsv1 MUSTENTER TYPE COMMENT AFTER ENTRY IF varsv1=1 THEN GOTO WRITE ENDIF IF varsv1=0 THEN RELATE idno file2.rec ENDIF END END I am not sure if this error message is related to a bug or typo. Your help would be very appreciated.
