How to check for duplicates

Support
1

Hello all,

I have been working to find a way to check for duplicates. It took me a
while to find a solution and a couple of posts here in the group helped me
(see the links below). I attached the file for others who need it.

Thanks

Nice one. Thanks for sharing!

Here is another one that doesn't use indexed-repeat (since indexed-repeat
isn't supported yet in Enketo) and performs the check as a constraint:

Hi Rofand

Is it possible to prevent a user selecting a select_one question more than once have some logic in the XLS to prevent duplicates of that variable

Thanks Martijn
I am facing errors when using the Enketo webform.
To duplciate the error

  • Add ID 1
  • Then add ID 2
  • Then add ID 1
  • Then Save: it says error
  • Go back and correct the Last ID and Make it 3
  • Try saving. It still gives errors.
  • Edit and change all IDs to 8, 9 ,10 and try saving:
  • Still error comes

Thoughts ?
Vivek

Ouch! Yes I see. My technique was embarrassingly flawed! Please discard it.
Sorry about that.
