Online service tax st-3 filling through xml uitility

Hi,

I am filling online service tax return through XML utility. We are providing two different services while service tax is payable for only one service.

After filling all the details and validating all the sheets, when I click 'Validate Return & Submit' it shows error 'Run-time error  '6': Overflow' and bring me back to the sheet 'Return' on Taxable Services Provided row.

If I delete one service from the sheet and click 'Validate Return & Submit' it generates the XML file without any error.

Please provide the solution of the same.

Thanks
