Welcome to the ODK forum, @Dolapo! We're glad you're here. When you get a chance, please [introduce yourself on this forum thread](https://forum.getodk.org/t/-/6671). I'd also encourage you to add a picture as your avatar because it helps build community!

It sounds like you may have an issue with your syntax. The XLSForm documentation is [here](https://xlsform.org/en/). When converting your form with [XLSForm Online](https://getodk.org/xlsform/) it should give details in the error message about what went wrong.

Can you share the `.XLSX` version of your form here? If you're using ODK Build you can got to "File" and then "Export to XLSForm".
