Hi Sam:
There are two approaches to double-enter: 1) independently, 2) the second file depending on the first. You seemingly chose the latter ("prepare for double-entry"). If you choose that option, you must enter the records in the same sequence (I believe) and the value of each field in the second record will be compared to the corresponding one in the first and a discordance reported, so you can verify. Thus, no need to enter twice.
Alternatively, you enter your related file pairs independently between first and second entry. You must have a unique identifier in both the parent and the child file. The sequence then doesn't matter of course. After you have entered parent1-child1 and parent2-child1, you validate parent1-vs-parent2 on the unique identifier, then child1-vs-child2 on that identifier.

Hi,
I have a questionnaire that uses two related .rec files for data entry. I want to double enter the data by checking for discrepancies as the data is entered the second time. Is it possible to do this for questionnaires that span two .rec files? When I try to prepare for double entry, the program creates a "file1_dbl.rec" file, but relates it to the "file2.rec" file rather than creating a "file2_dbl.rec" file to compare against.
I am thinking that I will just have to un-relate the file, and enter and double-enter the survey in two parts, but any help would be appreciated.
Thanks,
Sam
