if i enter 3 in a text box i have to display a subform with 3 rows of textboxes for name,age etc.

I assume you use ASP.NET. Why don't you build your subform dynamically in code and then have a loop and add three text boxes?

Sorry here is a sample:
int i = 1
While (i <= Int32.Parse(txtAccompanies.Text))
{
page.Controls.Add(new TextBox());
}

Cheers
