2. Challan does not exists (I entered correct challan number with correct format but it is shoowing error.

3. Source documents (I paid interst @13% p.a. and perahaps it asking for that. How should I enter this in return)

And what is the difference in (I) SERVICE TAX PAYABLE and (II) TAXABLE AMOUNT CHARGED. In which I should file the details?
