Hello. I am attempting to publish a survey but I am getting error code 400 - Unable to create folder. All values in the name field are unique, and I am not using any reserved keywords. I've tried deleting the feature service and the .iteminfo file and republishing, but this didn't work. I've also tried publishing a copy of the survey, but I receive the same error code. There must be a problem with the xls, but I've looked it over multiple times and can't locate any potential issues. The xls is attached. Please help. Thanks.
