I have an error on preview form for my questionnaires

When I do the preview form, It shows me that message. I try to refresh many times, but it always happens. I hope to get support from the KOBO community. Thank you.

Hi @mayen_1 and welcome to the community!

Can you validate your form in here to see are there any errors?

Thank you so much for your solution. I can find my mistakes now. After I fix it, I still cannot preview the form from my Kobo platform. However, I can only see it from ODK. Do you have any suggestion for me? Thank you so much for your help and kindness.

Can you provide a screenshot of the message you’re getting?

Ascii 8 is Backspace or this one ?

Good luck :innocent:

Could u pls help me?

@mayen_1, your screenshot is not visible. Maybe you could also share your XLSForm with the community. The community should be able to help you out.

Oh. I fixed it. Thank you so much.
