I have this following error and couldn’t resolve it. Need some help

Error: ODK Validate Errors:
[Fatal Error] :3:231037: The content of elements must consist of well-formed character data or markup.

XML is invalid. See above for the errors.
org.xml.sax.SAXParseException; lineNumber: 3; columnNumber: 231037; The content of elements must consist of well-formed character data or markup.

The following files failed validation:

Thank you in advance
