FormLogicError: Could not evaluate: /model/instance The expression is not a legal expression. (line: undefined, character: undefined)

CUARTA_OPORTUNIDADLOCAL — Mon, 22 Apr 2019 16:24:05 GMT

Conduct a survey on survey123 Connect, and publish it to be accessed from the web.
When I access the url, I get the following error:

FormLogicError: Could not evaluate: /model/instance[@id="Funcionarios"]/root/item[Número de documento = '']/Permiso de realizar encuesta de Licencias de Construcción, message: The expression is not a legal expression. (line: undefined, character: undefined)

I do not know what I should do to make it work, i need help.

Hi,

I see that the CSV files you are using have very long column names - could you shorten them and eliminate spaces?

As well as avoiding extra long column names, the columns names used in the csv file used for pulldata() can not contain special characters, dashes, spaces, accent marks like acute (é), grave (è), circumflex (â, î or ô), tilde (ñ) and must meet the same requirements as the name column and choice column in the xlsx form:
