Hi @pakilimali
We're glad you're here. When you get a chance, please introduce yourself on this forum thread. I'd also encourage you to add a real picture as your avatar because it helps build community!
Could you attach that form here (xls version ideally)?
What version of ODK Aggregate are you using?
BTW. Have you heard of ODK Central? It's our new server which we recommend using because ODK Aggregate is no longer actively maintained.
