Dear Kizito:

It is a good rule to provide complete information before requesting assistance. Your message is non-informative about the software

Does your question concern: - EpiData Entry 3.1? - EpiData Manager, and if so which version? - If you use EpiData Entry 3.1, could you show the part of the check file that controls the field?

Without this information, one cannot answer.

Dear Listers,

sorry I am asking this again, since I received no help yet.

I wanted to do data validation using the Double Entry Verification mode, but when I used an automatically generated unique identifier for the records using three field it could not prompt for correction even when there was discordance.

What is the solution?
