ODK Collect issues while pulling datas from CSV

1. What is the problem? Be very detailed.
Hey there,

I have to survey households who are members of cooperatives. I previously manually registered the names of all the members of these coops, with other information like their localization (districts > communes > villages) in the db_bnf. I now want the surveyors to select the members in a list, restricted thanks to the localization. As I have more than 2500 entries in the db_bnf, I don't want to copy/paste it directly in my choice sheet. So I put it in a CSV (an sample is attached) download it with my xlsform on Aggregate and pulled the data in Xlsform with the pulldata() function (please see the attached file). I then use cascading select_one to reduce the list of beneficiaries.

The importation goes well, but when I go on my mobile device to try it, I have the following error :
For each column called, I have the message error "No such table: externalData (Sqlite code 1): ,while compiling, : SELECT c_district FROM externalData, (OS error - 2: No such file or directory)

It's the same for the c_op, c_id-commune, c_commune etc.

Could you help me understand my mistakes?

2. What app or server are you using and on what device and operating system? Include version numbers.
Aggregate 1.7.3
Collect 1.21.2

Hi @Julien_GM

your xls form contains many problems and ca't be converted using http://opendatakit.org/xlsform/ the csv file doesn't seems good as well. If you want someone to help you please just attach a form that we can use for testing.
When it comes to pulling data from csv file you can find more info and a sample form here: http://xlsform.org/en/#dynamic-selects-from-pre-loaded-data I think it should help you.

Hi @Grzesiek2010 thanks for your fast answer. You'll find the corrected files here:sample_xlsform.xlsx (17.8 KB)
bd_bnf.csv (607 Bytes)

Thanks for the link, I read it at least ten times these past two days trying to understand my mistakes. I also searched on this forum and on ona. I found this example that helped me a lot.

Thanks again,

Your csv file doesn't seem good.
First off all remove those not needed ".
Then please take a look at this sample:

to understand the format.

If you want to get items for:
select_one op where name: id_op, label: op
your csv file should be like:


Thank you @Grzesiek2010, it's finally working. I just splitted my CSV in 3 files to make things easier to interprete.

If I may give some non computer specialist feelback, I think that the example you gave me is not that good. The 'fruits' is the CSV, the question's name and the choice_list. In my opinion it would be much easier to understand if there were three different names!
