I get this error message when I try to depoy my XLSForm
FormLogicError: Could not evaluate: round(( /model/instance[1]/asWmPRG4fC6tGWpEAD2Fhk/total_score /4)*100,1), message: Failed to execute ‘createExpression’ on ‘XPathEvaluator’: The string ‘./4’ is not a valid XPath expression.
Welcome to the community, @owuike! You could always validate your XLSForm through this online validator? The online validator should help you identify any syntax issues that are affecting the form deployment.
This post discussed previously should help you use the online validator.
When looking at the error message you shared, it seems like you are trying to use / for divide, which is not supported by the system. Instead, you will need to use div. For more details, please feel free to have a look at this support article, Advanced Calculate Question Type.
