Please Help: Problem in ST-3 Filing

While filing ST-3 returns for our client, for the period April –June 2012, we claimed SSI abatement of Rs.10 Lacs under notification no.006/2005-ST by clicking on the option as given in the drop down list on the first page of the new ST-3 offline Xml schema return. But after claiming the said abatement amount, the return is not processing and rejected with stating the error as "If no abatement notification no. is selected then, no abatement amount should be claimed" whereas we already selected the above notification no.

What should be done?

Further if 10 Lacs treated as exemption, not as abatement, then where to claim this exempted amount in the return? Any specific cell in the return? Client received only Rs. 1.50 lac during this qtr. And last year received amount also below to exemption limit.

Thanks in advance
