I have developed the XLS form for the cascade select option type, but the system is not running

I have developed the XLS form for the cascade select option type, but the system is not running. Can anyone help me figure out what I’m not doing right? Are there any limitations on the number of items the select option can take in Kobo collect?

Welcome to the community, @Sefa! Could you also share your sample XLSForm that has the issue with cascading select? Maybe the community should also be able to help you solve your issue.
