Query on quoting of Quarterly receipt no. on form-16

Hi,

Help me in understanding the correct meaning of  this

 "receipt numbers of all the relevant quarterly statements in case the statement referred to in clause (i) is for tax deducted at source from income chargeable under the head "Salaries".

My confusion is whether we have to quote all 4 quarters receipt no's on Form-16, eventhough the employee doesn't have the tax deduction in first two quarters.  Or shall we have to quote only those quarterly receipt no's where tax deduction is happend.

Please someone clarify.

Thanks

Anand
