Error message seen while previewing survey project

Hi @rahul_521,

Kindly please be informed that the image you share is related with duplicates in the choices tab. Download your xlsform and then scan for duplicates. You should see some duplicate values within your xlsform. Try removing them and the problem should be solved.

For your ease, you could test your xlsform here.

Have a great day!
