When I tried to validate my survey, i get the following error message and I am unable to spot where the error is.
Error: The name ‘1’ contains an invalid character ‘1’. Names must begin with a letter, colon, or underscore. Other characters can include numbers, dashes, and periods.
In my choices tab, choice names are listed as numbers (eg: 1 - Yes; 2 - No). But I have done this wothout getting any errors in previous surveys. Please advise how to porceed.
