I'd love to help, but your post does not contain enough information for me to answer your question. In general, the best way to get help is to fill out the questions in the pre-filled template that you get when you create a support post. So, with that in mind, can you answer these questions?

1. What ODK tool and version are you using? And on what device and operating system version?
2. What steps can we take to reproduce the problem?
3. What you have you tried to fix the problem?
4. Anything else we should know or have? If you have a test form or screenshots or logs, please attach.

Thanks to all, but I got it

Just so others could benefit, what how did you solve your problem?
