Preview entry error

There is an error when i preview my form

@selma_aa, maybe you will need to validate your XLSForm through this online validator to see if syntax issues are rendering this error.

i am building the form from scratch and not using XLSForms

I mean, you could still download your project as XLSForm and then validate it with the online validator. The online validator should be able to point out the syntax issues, if any.
