I am using ODK Collect and XLSForms to conduct a survey. I have successfully created and uploaded several forms so far, but have been facing a trouble with a specific forms. I am using Google Drive and Google Sheets to store the data (have been working great so far until now). When I send the forms, I get the following error:
"max number of columns is 255 - yours have 265. Unable to upload spreadsheet"
I can't figure out what is wrong, since this specific forms is no different from many others I have uploaded without problem so far. I also can't understand why would the number of columns be a problem, since the max number of columns for Google Sheets is over a thousand. My forms have 71 rows in the choices sheet. I have successfully uploaded a forms which had more than 300 rows in the choices sheet.
Any help would be appreciated. Thanks in advance.
