Dear Hilmar,
Thanks for ur answer. I shall try it. Thanks you again for your valuable advice which I have had earlier for my question. Your reply helped me lot in past. Now let me inform you that I am not much familiar with form,just trying it now for a couple of days.And for this printing, I am asking the user to enter account No. against which the user want to see the transaction details of a particular account.After geting the account no. I shall print the result in txt.And I was in a mind that for entering a single item this would be better. Yes, I may be wrong. But this type of error message is also unexpected to me.

Thanks again,
Chandan
